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 Sep 11 → 0.33/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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
Islets Defense is a turn-based tower defense game focused on resource management in which you build a small and efficient village to support your towers and secure victory.


A turn consists of executing one of the four available actions, each with its own unique functionality. The order of the cards plays a key role, with the rightmost card offering a stronger effect. After completing your turn, the chosen card moves to the leftmost position, pushing the others one step forward. Consistent and efficient use of all four cards is key to building a solid defense.


Allocate your towers in strategic positions, sustain them with food, upgrade them with wood and stone, and ensure a strong defense against the slimes. Chests and stage modifiers will offer new strategic opportunities, with unique towers and various upgrades to explore.


Each building has different upgrade options for you to choose from. Build the most efficient village by making smart decisions that synergize with your positioning strategy!


The mist has covered your entire kingdom! You start the game with an unexplored map, ready to be revealed! Use the exploration action to reach new resources, gain visibility for your attack towers, and discover hidden treasures!


Advance through stages, complete challenges, and earn diamonds and feathers to unlock and face different biomes! Islets Defense is the game for those looking for a classic tower defense experience mixed with the chilling vibes of a resource management game, all wrapped up in easy-to-understand mechanics filled with creative possibilities.

25+ different building structures, each with their own unique abilities.
A 15-stage campaign featuring distinct modifiers, level design, biomes, and challenges.
6 different upgrades available for many buildings.
20 different tiles scattered throughout the stages, each with its own unique and intuitive interactions.

I just finished it, that was fun. At some point difficulty jumped from 'do whatever and you win anyway' to 'oops I made a mistake I need to restart'. Infinite levels to check how long you can survive would be cool I had to retry last mission once, and it starts with relatively long unskippable intro, which could be annoying if I had to restart more than once.
this is not a "TD" in the basic sense its a ressource management and puzzle ish game level seem to all play the same way with only the four 4 of action per turn its totally fine mechanic but this game is not for me

Misleading tags. This game should be "Puzzle" and "Turn-based Tactics"
Fun little puzzley build-order-focused tower defense game. You have four different base buildings and can get various upgraded towers and buildings via chests/shops. Starts pretty basic and easy but ramps up nicely. Took me about 7 hours to get perfects on the base game (15 maps) and there are hardcore versions after that, which are more difficult. You will have to restart some maps because there's no undo or save, but maps generally top out at 30 min a pop so it's not super onerous. Not going to knock your socks off, but it does everything well with no bugs and a pleasing presentation. 8/10 edit after 100%: took another 10 hours to do the hardcore versions, some of which are quite tricky. If you're the type that likes a build order puzzle, this one will certainly scratch the itch. It's nicely refined and well worth a look.
3/10 on the slow side
I don't like to review games unless I get very far into them or beat them, but I don't know if I will ever get far enough in this game to do so, so I'll just leave a review now. I'm rating this positively but I do have some concerns. Let me explain. The game is looks fine, animates well, is entertaining in many ways, and carries relatively a high production value. I like that it works well with controller and M&K and is steam deck ready. It's a pretty challenging game and it appears to have a lot of levels and objectives, so the value is definitely there. My problem is that it's not that fun. It's kind of a tower defense game but you also have to manage an economy. But you're not given the freedom that you think you'd get in a game like this. Every round gives you one thing to do. So you can't build towers every round. You'll also have to manage your resources and if you go dry, your towers won't even fire. I was more frustrated and bothered by these mechanics. And it's a shame because the game looks like it could be fun. Ultimately, it's more of a puzzle turn-based game than a traditional tower defense game. In fact, it seems that to progress and get all the optional objectives, you'll have to play a certain way. I hate that. I can't in good conscience give this a thumbs down because it is a good game. I just wish it wasn't so constraining with it's gameplay elements.
回合制塔防,机制还挺有意思,整体流程也不太长,不会太重复。通关了也不想玩高难度了,总的来说值得推荐。
Fantastic, I crave more, please give me expansion packs
It's a fun take on tower defense. For me, the difficulty was perfect. Not too hard, but had to retry a few runs.
This is an excellent little game with a minimalistic style but a surprisingly complex balance of resource management and strategy. There is some room for improvement, an endless mode would be a great addition, but it is a very solid game. 6 Thumbs up!
