Just realized I haven't updated this topic in...quite a while. So much has changed!
-Controller support is in. Specifically Xbox 360 and Xbox One controllers. (keyboard support has been removed, because..)
-The game is now 2-4 players instead of just 2
-The game has received a WHOLE LOT of visual changes and updates since I last posted. It's basically a different game now.
-A new attack type has been added: you can now fire projectiles
-You can now choose between 8 levels.
-SumoBall has been removed (I may actually spin it off into an entirely new game after I'm done with this one)
These are all the major changes, although there is a whole bunch of smaller ones that you'll have to see for yourself.
The game is almost complete, it just needs testing. If you guys have two or more controllers and friends to play with, and want to test this game, let me know! It would be greatly appreciated.
Here are some screens of the game so far:
