Hey, you have probably stopped production on this game, but I would like you to know, a level editor, a few more tiles, and some of the following powerups would be cool:
~Some sort of tile randomizer, just to shake up the game a little bit :D
~A location switcher, that switches the locations of players (plus a slight invincibility period)
~A random powerup (just gives you a random one)
~A slowdown (either like the speedup, but opposite, or a time slower)
Thanks for reading my comment. I really have nothing bad to say about the concept, and I love playing it with my friends. If you are still working on the game, I just want to say that I appreciate what you are doing and would like to thank you for giving me a fun multiplayer game.
