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.
About
Slay All Bosses: Idle is an incremental RPG where you take a lowly level 1 hero, barely capable of handling a pack of lesser goblins, and forge them into a legendary slayer able to defeat the deadliest of foes.
Your selected hero fights automatically, attacking enemies and unleashing powerful Weapon Skills. Weapon Skills are tied to the weapon you have equipped, but after enough uses they are permanently learned, allowing you to freely swap weapons and experiment without losing progress.
After every battle, you earn currency used to advance your hero’s skill tree. Skill trees feature a variety of nodes, from raw stat boosts to gameplay-altering passive abilities that redefine how your hero plays.

Each time your hero levels up, they gain Skill Points used to unlock Weapon and Skill Upgrades.
Weapon Upgrades provide additional stat bonuses when equipped.
Skill Upgrades allow you to enhance your learned skills even further. You can add status effects, strike all enemies, and/or reduce cooldown times. Spend Skill Points to transform skills into devastating tools of destruction.
Your hero will face enemies armed with lethal skills and dangerous status effects. Equip accessories to gain passive bonuses and resistances. After enough battles, you’ll permanently learn these passives and can equip them freely, limited only by your hero’s Ability Points (AP). Mix and match learned abilities to adapt to any challenge.
Strategic auto-battles.
15 challenging boss battles.
A satisfying progression loop that seamlessly blends character, weapon, and skill upgrades.

the game sucks, it had potential but seems like at the middle of development they just thought to make everything "cheap" and fast in terms of development effort. after 30% of the game all the upgrades start being irrelevant, last 70% of ring abilities you gain are just "ignore x status effect", such a small game somehow included 20 status effects.
El juego no me graba la partida y cada vez que juego tengo que empezar de cero

Maybe I misplaced my expectations, but this game was way too short. It's also not an Idler game as the "Idle" in the name suggests. This is just an auto-battler RPG with pretty monster art for $5. I think it's better to review this based off what they advertised as "featured" content: 1. Strategic Auto-battles - they're not strategic. Most of them are just "slap damage together and hope you get good potion drops to fight the boss" battles. It doesn't help that there's nothing to interact with once you're in combat. Sure you can manually use potions instead of toggling auto-potion, but auto-potion bypasses your APM limits and 95% of the time manages to use the potions with 100% efficiency. Also all the customization lies with your weapon and upgrades to it, but even then there's no real customization because the game forces you to choose the next meta weapon anyways to progress. 2. 15 Challenging Boss Battles - Again, not really challenging. In a auto-battler where the whole point is to upgrade your stats in your skill tree, Typically you want 5-9 upgrades per boss to safely pass the stage with RNG in mind so it's extremely linear. The only challenge is clicking your finger away to unlock the nodes in the tree. 3. Satisfying Progression Loop - This is the ONLY "as advertised" part of the game that's somewhat correct. The only upgrades that felt satisfying were the character stat tree only. The weapons, relics, and the skills were boring. Everything else in the game is negligible. If you want an easy time, go the swordmaster, if you want to suffer, go assassin, and if you like flashy special effects, go sorceress. That's all this game boils down to. At least this game is just $5 if you want to add something to your list of platinum achievements which is what I ended up doing.
I'm gonna be honest, this game isn't... *good*, per se. As others have said, you kind of just sit back and watch numbers go up. The tree is samey, the balancing is questionable, the Assassin literally does not even have a kit that functions in this game (it's based around applying status to yourself... except there is no way to intentionally do that), and most fights boil down to luck and throwing yourself at it repeatedly until you happen to win. ...but the numbers. the effects are satisfying, the SFX are crunchy, the numbers go up... I want more. I played this until 100% completion and I still want more. If the dev makes this, more of this, but with more polish, more content, just more of THIS, i will give them my money.
A decent incremental game. It's not an idler by any means. There's not much replayability but you only have to grind the entire thing out once. The other 2 attempts if you want 100% only need to go part way.
First of all. This is a good game. Beat the game on all 3 maxed out characters and have all achievements. I would agree that the balance on this game is not perfectly ideal. On my runs, I found that the assassin is the most OP on all the characters because of the poison. I don't know what versions others played and reviewed but the bosses literally dies faster because of the assassin's poison. The grind is ok since there are fast forward functionality in the game, like those in recent remastered Final Fantasies. To summarize: Gameplay: Like any autobattler, you sit down and do management while your character is fighting. It is better to be on manual on items if you need to be efficient then on auto when you're on grinding. You manage your skills depending on the boss to be efficient so you wouldn't have to rely much on grinding. Basic rpg rock paper scissors, good sh*t. Pacing: OK! much better to be on manual input on the items on the first half then auto on second for grinding. Achievements: it takes a while because of the 10/10 on all bosses but it's not that complicated. once you beat the game and maxing out your character, like any other rpgs on trophies/achievements. there is grind and repetitiveness.
Great game needs more skill tree and a reason to push on im not on the last boss and full completed the skill tree and daggers. Again amazing game! just needs more for content
流程很短,内容很少,整体游戏非常简陋,最多只值5块钱。
Super fire !!! Love this game, perfectly done.
