One suggestion; it is pretty difficult, but it is labeled impossible so I'm not surprised. If its a single difficulty beatmap its fine, but if you want it to be accessible to more people, then more difficulties to choose from would be nice :) other then that, it was fun :D
Also, as I mentioned in the comment, difficulty increase between Normal and Hard is pretty steep
You could either just leave it the way it is pr make the Normal difficulty Easy and create a new Normal difficulty. It isn't a huge problem, its just something I noticed :)
FUN beatmap WOOOOO good luck on getting it ranked, overall other then the things I mentioned in the comment I think it was great :)
Okay, it’s cool, I get it. I just thought it was something to point out :) good luck with the project, I’m enjoying it so far :D
