I haven't played Disc Room yet, but I don't think I need to, because this game is my jam! At first, I didn't like it too much: thought it had too many controls to juggle and it didn't explain enough about how to play (definitely didn't explain that you respawn with R, haha) and it was just odd to get used to doing double-duty, piloting both the person and the cannon. But boy, once I played it a bit more, I got in the zone and had a ton of fun! Seriously, once you get in a trance and you're able to pilot both the little guy and the cannon simultaneously, it feels great and is so fun to get skilled enough to do it! Would love to see this get polished up a bit more with some more instuctions and juice, like animating the roll a bit better and making the walls smoother so you don't get stuck, as well as maybe giving some more feedback: similar to how you have discs get bloody if they kill you, I'd love to see discs that take multiple hits go through stages of damage so you feel like you're making progress blasting them. Nice work!
Oh yeah, how could I forget: the music is dope as heck and really amplifies the experience (and nice touch on slowing it down on death)!
