I finished OneShot tonight. It originally came out in 2014 as an RPG maker title that recently got a Steam release. I decided to give it a (haha) shot. I was hooked and I really enjoyed it! The protagonist, Niko, is such a sweetheart and the game makes you care about them a lot. I don’t want to give anything away if anyone wants to play it. That said, I see a lot of comparisons to Undertale flying around and it’s understandable as both games have a similar general direction and use meta mechanics. However, they’re fundamentally different games and OneShot has it’s own identity.
The way I see it, OneShot is less Undertale and more like the Madhouse anime, Kaiba (not YuGiOh). I can’t really say much about the game without spoilers, so I really do recommend giving it a playthrough. It’s really short and won’t take you very long.
