The polish and the presentation in this game are top-notched and I'm shocked those screenshots/gifs haven't resulted in more ratings. The opening cutscenes was great. The fact that it's fairly ambitious with save points, branching paths, and boss battles is incredible. Unbelievable amount of work and care went into this in such a short time.
My only criticism is I found the lack of gravity more frustrating than fun. I found myself avoiding the launch if I could, which is unfortunate because the levels/bosses encourage it. I think it can be fixed with a few tweaks, like perhaps less floating after launch or a quicker return to the ground. For example, I would often wait to hit the ground before I shot so I didn't go flying, but it took too long to start walking again so I found myself shooting myself backwards. I think just a LITTLE more tightness and control would go a long way.
Overall, incredible. You'll be getting some of my highest marks. Amazing job.
