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.

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.

Peng, bottom of my heart, thank you for making this. Team, great work. I specifically noticed the QOL on fail-state on a certain boss, little touches like that? They separate the real guys from the fakes. This game is a visual novel with modern-recreated-retro-style graphics with gameplay of a very easy, and I mean very easy, rail shooter. Brutal honesty? The meat here is the character designs, the story, the music. The story here is awesome. It aligns with media like Alita Battle Angel, Eva, Umarangi Generation, Nier. My playtime was 3.5 hours for 10 USD and I feel that's absolutely fair. This game is incredibly great at emotional hooks. The beats here, the emotional whiplash, its insane. Its not for everyone to be sure but I really really adored this and I want more people to experience this story. I really will be telling all my friends about this because this deserves more eyes.

TL;DR version of my review: if you can get it for like $5, like on-rail shooters and VNs, go for it. the visuals are great. but if you're expecting any sort of depth (gameplay or story-wise)... this may not be for you. I'm giving it a recommend because I like the idea, but you have to go in with LOW expectations. This game had so much potential. the beginning of the game set up some cool ideas, but it kinda just left them... The characters never felt fully fleshed out. The gameplay is pretty fun, but lacks ANY depth what soever. there's a "shop" where you can upgrade between some missions, or when you die, but theres no connection to the story. its never explained. it seems like the shop was meant to have way more to do in it, there to be more weapons, and other upgrades, but they either ran out of time, or forgot about it. The gameplay is super easy. the only reason I died is to see what would happen when I did.... a game like this should be WAY way harder. This game needed another year to develop. It could have been a real indie classic. As is, it feels very unfinished.
ビジュアルノベル&擬似3Dシューティングゲーム☆ ストーリー部分、シューティング部分共に面白くクオリティの高い作品です。 まるで一本の映画を見た感覚でした♪ ストーリーを把握したうえで2周目プレイすると、色々気付かされる点に驚かされます。 キャラクターも個性的で可愛く、シューティング時の操作性も◎。 雰囲気にマッチしているBGMも、とても良かったです。 ストーリー重視なのと難易度が低めなのでやり応えを求めている人には向きませんが、気軽に疑似3Dシューティングを遊びたい人にお勧めです☆彡
While basic in terms of gameplay and story, ULTRA0 is sincere, doesn't overstay its welcome and isn't too pricy. Good enough if you want a somewhat soppy story about superpowered schoolgirls. Although the inconsistent dot pitch is unforgivable. If you're going to make pixel art, make it at a consistent scale.
I wasn't really expecting much when i bought the game. It looked like one small and simple indie game trying to tell small fun story with just as simple gameplay. That's why i was more than shocked to see how much milage they got out of such a simple gameplay to tell a really exciting and engaging story. By the end i was really crying from both excitement and overflowing feelings and the final moments really stuck with me. I know i'm probably biased because it's yuri but it turned out to be one of my favourite indie game experiences of 2026. I played on Steamdeck and everything works perfectly smooth.
Interesting and fun short game. Would say the story overall is kinda underbaked but ultimately it did have me emotionally invested. The way it uses gameplay as a method of storytelling was real cool, lots of little moments that hit harder. English translation was a little iffy/overly literal at times but still competent. Would recommend and interested in what the dev makes in the future! (reina best girl)
This was a great experience, easy to play, enticing story kept me hooked, really enjoyed the character depth plus it has some lovely background work. Definitely recommend especially at this price point.
The ending felt slightly confusing, but overall the story was very cute and yuri, and had funny moments to go with the gut punches later on. Fully playable on Steam Deck.
I wish more people knew about this game. It's pretty cool!
