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): 0.29/day in the week to Aug 21 → 0.71/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.

Fun idler! A few levels took more thought but it's nice to work through the prestige tree
2,6h to finish, nice dopamine
Told my fiance I wanted a mindless idle numbers go up game with a skill tree, this was exactly what I needed this weekend. Something that sets this game apart from others is that you progress by meeting a killstreak instead of by not letting enemies reach your tower; this is less disruptive to game flow and has made this game really enjoyable.

Ничего интересного. Однообразный геймплей под ещё более однообразную музыку. Вам не нужно проявлять никаких тактических навыков. нужных для "Tower degence". Вы даже проиграть здесь не можете. Просто сидите и копите деньги и даже с самой кривой расстановкой башен - рано или поздно выиграете
Very fun and interesting especially for the price. Setting the attack priority of the towers is essential to advancing in the game. When I first played I did not know you could do that.
短時間で満足できるので価格相応に楽しめて満足! ビルドもいつでも取り直せるし、カスタマイズの試行錯誤もやりやすい ちょっとした時間でタワーディフェンスやりたいと思った方は是非!
Juego idle chill de unas pocas horas de juego tranquilo. Se podrian añadir mas niveles para estirarlo mas.
Guter Start, verkümmert im zähen Grind Der Einstieg in dieses Incremental Game macht zunächst Laune und vermittelt ein flottes Gefühl von Fortschritt. Die Ernüchterung folgt jedoch schnell: Echte strategische Tiefe sucht man vergebens, das Ganze verkommt zu planlosem Trial-and-Error. Sobald die anfängliche Dynamik verpufft, gerät der Progressions-Loop ins Stocken. Statt taktischer Entscheidungen heißt es nur noch Warten, bis genug Währung zusammengekratzt ist – nur um dann festzustellen, dass die mühsam erspielten Upgrades und Prestige-Zuwächse kaum einen spürbaren Schub bringen. Nach etwa 6 Stunden war bei mir die Geduld am Ende. Wenn ein Idle-/Incremental-Spiel weder eine befriedigende Skalierung noch echte strategische Optionen bietet, verliert es komplett seinen Sinn.
Pretty fun overall. Like most TDs it's kind of basically a puzzle game, but it was still a nice experience.
This is a puzzle game designed as a tower defense game. The difficulty in combining different prestige skills and the satisfaction of the broken prestige skill in the end game made this game good albeit short.
