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.
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)
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.
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.
cute game
