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): 0.57/day in the week to Aug 27 → 0.14/day in the week after.
Reviews, worldwide (the counter carries no country): 0/day in the week to Jul 19 → 0.86/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.

I got Ultra0 on a whim since it was on sale and ended up enjoying it, although the story is quite grim. Since it's a bullet hell, I was expecting the game to be either harder or longer, but you can totally beat in one sitting. This is foremost a storytelling game, the gameplay is secondary. I don't know if it's a bug or intentional, but sometimes the enemies can stunlock you, and your character stands there like a dofus tanking every hit. The art style is cool.

一応最後までクリア、まだ実績コンプまではしてません 難易度に関してはスペハリがかなり苦手な私でもクリアできるくらい 基本ストーリーを読むのがメイン そのストーリーに関してはまず百合風味であることと後半が長めなので注意、最後から手前のシナリオは時間の余裕のある時にやりましょう 内容は中々きつめな話ですが最後にはカタルシスもあります 個人的には予想外に楽しめました

劇情非常好 射擊部分不難但還是會死 不過自動存檔的點很細 而且可以中途強化所以不會卡關 推薦給喜歡可愛女角的所有人
曲良い!!!
Short and simple on-rails shooter where the story falcon punches you while the soundtrack bangs your ears. Not too difficult and by the final boss you are able stage dive orbital KEWs like a pro soccer player. Hopefully the devs add the soundtrack as DLC with lossless option.
started & finished this in 1 day & it might be one of my favorite games now. while the gameplay itself is nothing groundbreaking, it's still really fun & easy to get into, even for casuals. the story is the real star here, it's well-written & i found it impactful enough to tell all my friends about it & leave review, which isn't something i really do. u can beat it in a few hours & the price is well-worth it. i highly highly recommend this one if ur a fan of yuri-tinged stories where everyone is suffering in some capacity
cute game
夢中で最後までプレイしてしまいました。 ゲーム難易度:普段シューティングをプレイしない私は、ヒリヒリする場面はありましたが、それでもクリアできました。 ゲームの物語:最高 愛と絶望とで胸がいっぱいになり、人のもつ愛憎や感情のもつれを描くのがなんてうまいのだろうと、プレイ中ずっとドキドキしました。キャラクターやその関係性の濃さ、ねじれが最高です。 おかあさんを探すうなぎの赤ちゃんをわたしも吸いたい。
いい作品でした!出会えてよかったです!
