Seeing as this was the first submission, I've messed around with this one quite a bit and I think you have a SICK idea and an awesome start. I think your tutorial area is genius, teaching the player the fast fall mechanic pretty much instantly. Honestly, more games need a fast-fall mechanic like this. It really does feel good to SLAM down onto a platform and start flying. The drum sound really does wonders to amplify the game feel when you hit the fast fall just right, great stuff. The controls are slippery, but like juuust the right amount of slippery? IMO part of the challenge came from feeling out how long you gotta press the keys to make the ball go where you want, and after a little while I had it down and it felt good being able to chain bounces together. One thing that sorta confused me was the shooting paddle mechanic. The fact that it hurts you if you touch it when you go to shoot the diamonds dissuaded me from really using it at all, so if there was ever the option to go around the platform with the diamonds, id just go around. Especially when I realized you could screen wrap, which is a really smart design choice. I also encountered a few weird issues with some of the platforms stopping my upward momentum when I hit the underside which would send me falling to my doom. Idk how intentional this was, but when I started to get up there in terms of score, I saw less and less platforms, which I think is a super smart way of subtly increasing difficulty, but there were a few instances where I was put in situations that were pretty much unwinnable around the 8k mark. But also, I am dumb so there could have totally been an obvious out that I was missing, so take that with a grain of salt.
All in all, you got something cool here! Idk if something was stopping you all from working on it more, seeing as it was submitted almost two weeks early, but I would love to see more!
