The control button to attack, really? It's a bad choice, it is in an awkward placement. Also it doesn't really work all that well for attacking an enemy that looks just like you.
When attacking it's a clumsy guess at best.
The map is soooo small, and the two mushroom/lollipop portals do nothing.
I can see you improving this to make it a real game, but as it is.....BLAH.
