Discounts
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 → 0.43/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.
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.
10+ hours of playtime!

Wirklich tolle Kombination aus Tower Defense und Rundenstrategie. Sehr abwechslungsreiche Level mit individuellen Mechaniken.
Piccolo ma grande Tower defense. La parte più azzeccata è la gestione delle risorse che rende ogni partita molto strategica e mai banale, oltre al fatto che la "nebbia" nella mappa renda ogni livello un mondo da scoprire piano piano.
Impossibile, ti servono costantemente troppe risorse.

Great minimalist TD. Progress carries over from demo too.
游戏挺好玩的,就是内容太少了,塔的种类和关卡不够丰富,看起来以后也不会更新了,慎入,建议先玩demo
It's a really fun kinda cozy turn based city builder. The difficulty spike is ridiculous though. It's quite easy for the first 10 levels and then all of a sudden outta nowhere comes an extremely difficult one that I can't get past after a dozen tries. There are no difficulty settings not tips & tricks in game. Fun while it lasted though.
This game has exceeded my expectations! It's been a long time since I've played a tower defense game, and I figured I may as well try it since I got it as a mystery key online. I have so far finished the first three biomes and it's crazy fun, the way it manages to keep things fresh with biome-specific gimmicks, random minigames and traps for the player made me appreciate how well the developers managed to entertain the player through this tried and tested game format with a great spin. I also enjoy the turn-based, resource management aspect of it as it makes you think how to balance things out, and while I haven't much tried to take part in the leaderboard or hardcore mode, they seem like great ways to boost replayability and you just can't help but start to wonder how you could beat your PB, which is great. Criminally underrated, I'd encourage anyone to give it a try!
