I really liked the bumpers!
It took me a while to realize that I could jump. Usually I read the instructions, but I totally failed to. So that's on me. But regardless, I prefer to jump using the up key over X. But that's just personal preference.
The sound effects messed with my ears, but I think that's a me problem. I've had a lot of games do that with super repetitious sounds.
I really liked all the different gates, power ups, and the bumpers. Well done!
