Man I am SO sad that you didn't manage to submit this project in time: it is literally one of my favorites I've seen so far. Everything from the pixel art to the ambience, to the music to the design, I loved everything! It reminded me alot of hollow knight but underwater and with a rocket xD
Maybe the final boss was a bit tedious: I would have given him less health but this is really my only complaint.
Loved it very very much, for me, personally, it is the winner of the jam :3
