Prices
The United States storefront in every case, so this compares stores and not countries.
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 Aug 10 → 0/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.

Great game for the Steam Deck, just takes a little fiddling to get working. (For those wondering, switch to desktop mode, open the game, at the launcher uncheck the windowed box and set the graphical level to Fantastic then launch the game. Once you're in then quit and go back to game mode. From Game Mode launch the game like normal, click on the touch screen to hit play and run the game from there. To exit the game you have to force close it after saving, press the Steam button + B and hold until the game closes.) Neat game, neat setting, fun gameplay loop, cliche anime cast of characters but I enjoyed it a lot. Wish there was more endgame content but it is what it is. My only real complaint is the lack of Achievements functioning in the game. They need to fix this and make it easier to run on the Steam Deck without the workaround I posted. Hope we can one day see a sequel to this. FIX THE ACHIEVEMENTS!
他の人と逆の感想を持ちました。 マウスキーボード操作できないのはその通りですが、コントローラで操作する前提でちゃんと考えられたUIしているのでストレスを感じないし、ゲームのテンポ自体も全く悪くないです。(イベントシーンも大半はスキップ可能) まだ序盤ですがゲームシステム上、そこまで戦略性は高くならなさそうなのでがっつりしたタワーディフェンスを望んでいるのなら多分向いていないかと思いますが、カジュアルに楽しみたいのならセール価格分の価値は十分あるかとおもいます。 難点を上げるとすると、[url=https://steamcommunity.com/app/450250/discussions/0/352788552267253878/]コミュニティハブにスレッドもあります[/url]が、実績が機能していないこと。

Fun and creative tower defense game, but its a bit messy to play with a keyboard and mouse. The controls are much easier with a game controller. Achievements are also not working as intended as of this date.
While there is not too much too this game being just tower defense and some light story, I would still recommend it. Mainly for the likable characters decent writing, good tower defense, and the fact that I just flat out had fun playing it. Is it worth $20? Ehh.. but I got it on sale with my Humble discount.
Got this on sale, beyond that broken porting mass it's solid gameplay with wifu in it. Pros - Unique TD gameplay (as far as I know) you don't build and let's thing play on its own, it has some micromanaging which is engaging. - A mixed between city building and tower defense - Has a lot of building Variety. Cons - Long introduction and game won't let you go to setting until mission one which is quite annoying. - Abysmal keyboard support they even bother to include mouse control, controller is a must. - Achievement won't work - No support from dev, which is sad because this game has a lot of potential. Note I've play about 5 hours before writing this, I have not yet encountered any ingame bug. TLDR Fun Tower Defense game, get it on sale and you won't regret this (If your expectation wasn't so high)
Бои долгие и нудные. Нет ускорения боёв. Болтовня долгая и нудная. Нельзя пропустить все диалоги сразу. Фразы впиханы куда только можно было. 80% времени тратишь нажимая на энтер, этакий кликер. Достижения не начисляются. Карточек нет Игра однообразная.
I have owned this game for awhile and love tower defense genre. I was very surprised at this game as it takes it to whole new level. The characters in this game are very comical and interesting. This literally puts the story into the tower defense genres with great anime styled graphics and intense boss battles.

It's an OK game. With a good sale (75% off) and a controller, I can recommend. The game is a tower defense game with a bit of city building element to it, by making you plan for configurations you can use during waves of enemy invasion. There is a linear and almost boring story line, but I enjoy the not so serious attitude. Overall a good time killer.
