The game is pretty fun and I like it quite a lot, but I do have two things that I can think of that I would like to be added or changed.
1. The perspective. This may just be me not looking hard enough, but I find that it is often hard to judge quickly how far or high a platform is, which makes it more difficult to make jumps and safe yourself from the wrath of gravity.
2. Combat. I really enjoy the idea of cutting the floor and trying to kill people by making the area unplayable, but I think that having a way to attack people without having to destroy the battlefield would help. Even just a way to push the enemies into the void. That'd be pretty cool in my opinion.
Of course, it's your own game and you are the one who decides what goes into the game or not, and the game is really fun as is, but I'd enjoy it a lot more if either of these things or more were implemented.
