Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 15 → 0.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

*Experience the Ultimate Tactical Battle in 1-on-1 Command Combat

*Strengthen Your Mamon Through Training, Tournaments, and Expeditions
Training isn't the only way to hone your Mamon—it's also about deciding what to do each week at home. Mamon grows stronger not only through tournaments against rivals but also via Expeditions, where you advance through uncharted lands rumored to hold ancient Mamon in a board game-style format.
*Your Unique Mamon
A Mamon's potential blossoms through your skill and luck. Inheritance Summoning passes on the power of your trained Mamon. And with help from a shady scientist or a muscle-bound trainer, your Mamon might gain powers beyond its natural limits?

Experience a new kind of raising in Mamon King!

tldr: buy the game for a few hours of fun; don't buy it if you are expecting a flushed out RPG It's fun for a few hours! It's not a bad game at the price point, but the game severely lacks depth. The gameplay loop is straight forward to the point of being quite tedious: almost all your days should be training a relevant stat, some days do something a bit different like expedition or item battle if it's a lot of gold, over level before progressing onto next rank. The combat itself is also quite simple. It looks like a card based combat system like slay the spire, but it's more like a 6 slot move system with a mana pool. there's very little depth to the combat; most of the time it's optimal to click one move, maybe a set up move is technically more efficient sometimes, but at the end of the game, it's a 1-2 turn kill meta, so setup isnt actually that amazing. creature selection is very limited, the gold system is not really that great (you never make that much gold. it's hard to afford items that are objectively not even that great and it feels very bad to not train and instead do a combat for the equivalent of the lowest tier boosting potion in gold. you can only acquire new creatures by paying a bit of gold to roll from a pool of ~10-15 per portal. you'll see basically every monster in combat by the time you hit the 2 hour mark, bar the final bosses. you probably will not beat the game without ending up feeling a bit bored - the gameplay loop is very uninteractive and linear. there are UI animations that make it feel even longer.

I really respect dude for making this game. It is however... really not all that good. It becomes boring quite quickly and is horrible balanced. It does however have it's charm and the cost is low and such I do not regret buying it despite it's lacking gameplay and balance of said gameplay. Everyone should be warned however that what you are doing is support a passion project. If you just want to buy a game to have a good game to play look elsewhere. No seriously, I cannot stress enough that this is not a good game. Most of the gameplay will just be you pressing X or spacebar on repeat while fighting from time to time. Then while you fight you will desperatly wish that you were playing a game with an actual combat system. Quite literally the only reason I am giving this is a thumbs up is because it is cheap and a passion project, not because the game is actually good or fun to play.
If you are looking for a modern variation of Monster Rancher, you have found it. Summoning appears to be randomized but based upon colored gates that can be unlocked through in game "voyages". There is a system for combining summons. Battles are turn based. The gameplay loop is satisfying if you're a fan of management sims, or were a fan of Monster Rancher. Train->Battle->Rest Over and over, until your heart's content.
I'ved beat the Mamon King! I used Kuranatur and built its HP, SP, Power & Defense. I only used Full Armor Skill each - a skill that lowers your evasion but greatly increase your defence (10 rounds) so he only damages me at 2% in total 10 rounds and when Voltras don't have mana he uses equivalent exchange skill which damages him at 5% to restore 100% of its mana, so at the end i won based on HP Percentage!. I'm So happy to beat the game and become Mamon King. Now I can summon Voltras in Jade Circle! Thanks again developer! I'm so happy to bought it because i really love Monster Rancher. I have the Complete Version of Monster Rancher from Playstation to Nintendo. Thanks Again!!!!
正直色々とチープだなって思ってたけど、やってみると育成が面白くて気になりませんでした。 周回、やり込み要素が増えたら良いなと思いました。
My negative review comes with a touch of remorse. I picked this up in support of the creator and his story, but I can't in good conscience recommend this. This game lacks any real depth or variability. It takes a bit of time to understand the abilities but even then, it's not that fulfilling. I haven't experienced any sort of evolution mechanism. The Mamon's you kind of just raise until they get old. Then you put them away and inject them into another card to feed it. And you repeat this cycle until you get strong enough to progress through the opponents. There's no exploration really. The mechanics are very repetitive and dull. It just falls flat. It needs a lot of work to have the playability one would want. I got through the campaign so to speak, and some of it was very frustrating because of how heavily RNG based it can be. A lot of save scumming. This game is like a gambling monster rancher. It's just too shallow and frustrating.
把モンスターファーム系列跟一點點實況野球系列的優點抓出來 搓的很好的小品遊戲,完成度很高 雖然戰鬥跟訓練的策略沒有MF那麼多樣化 考慮到價格,這是即便原價買了也不吃虧的作品w
its ok but i mostly got it cause it seemed like a mario party type game but no you only get access to it the mode once every now and then and only one attempt when ever it DOES show up :(
テンポ悪い、面白くない
This game has potential for sure but its more akin to Monster Rancher at home- not bad but like... just get Monster Rancher instead if you can. Its a recommend, but with a heavy asterisk in bold. The combat depth is nonexistent as you basically just want to spam the same move over and over again, you only really wanna do boot camp until you get the attack you might want (and you might not even need it to begin with- your basic attacks are fine enough as-is and will evolve to much stronger versions if used enough), and the expeditions which are sort of like a board game in which you can get a lot of stats in one go for a single in-game week, or even unlock a rare monster breed. Basically you want to just keep training and only really need to do the official cups and the gate unlock cups. Past that, just train over and over and over again. This is kind of boring if I'm being honest and lacks the charm of watching your monster simply vibe and do their thing. Don't let the cards fool you- they're purely an aesthetic choice. You don't draw from any deck, you don't have a way to get new cards, you don't discard any cards, they solely are just buttons on a menu, nothing more. Summoning is... frankly not good. For starters, you're required to pay in-game money to pull one at random from one of three gates, and no way to influence your choice. Yeah, you read that right- its a gacha system on a paid game, thankfully not using real money but also why make it gacha to begin with? This also means there's no way to zero in on a specific monster you want and you will almost surely be forced to raise whatever you get or start a new file because you didn't get to pull something you'd rather have. This only further hampers the fun factor and loses the whole wonder of summoning that Monster Rancher has. So why do I recommend it anyways if I've so far only had complaints about it? Because for all its faults, its a pretty cheap indie game based on Monster Rancher and it absolutely has good potential. None of the complaints I've mentioned here are necessarily severe flaws so much as little things that bother me (save the gacha bit, that needs to die) but there are a LOT of them. Not enough to make the experience unfun, but enough that it does mar the whole somewhat. If you want a quick hour or two of a concept that could work and just could use that little bit of polish, go ahead and buy this game. But if you're looking for a more fleshed out monster raising sim, just go play Monster Rancher DX for double the price of this (and double the games too!). And LiTMUS: Don't let this demotivate you from trying again or improving on this game. I'm harsh here only because I care (heck, its why I even took the time to type this up at all.) Your game is not bad, its okay. But just okay, and I have confidence you can make it better or use the experience making this one to make a better one down the line.
