Sweet, thanks Master Doot, your comments are very fair. I'd struggle to class the upgrades as collectibles since you don't collect them, they just upgrade your character, but to say that they're underwhelming is fair, I originally wanted them to be more spectacular but the gameplay I had committed to somewhat limited me :/. The controls were one button but that's not really what the "controls" category is about, it's how satisfying they are to use and how responsive they are, which I thought was pretty good in my game, but very subjective since it's about gravity so at different moments you'd want it to be slower moving. I'll definitely agree with you on the visuals, it's very technical-focused rather than art focused, but I still put a lot of effort into it. I really want to say thank you for the nice thing you said about the music, I'm not usually too good at that so it's nice to hear somebody liked it after all the effort I put into improving it. I'm glad you think the gameplay is good, I really wanted to focus on replayability, but I think I sacrificed skill somewhere along the way, and a lot of how to win has ended up being luck. Again, thank you so much for taking the time to write such thorough criticism! It's very useful for future projects!
