I like this game. Now it only needs a bug fix of the fact that one can just float in the air instead of falling off the building (see the image) and an online mode. I suggest to make the online mode so that there are 30 seconds to decide the next move.
I also suggest to move all the cards of the same colour one next to the other and to add a second evade that would be counterclockwise, unlike the one that is already here (so that when the falling off the arena is fixed, one isnt doomed if one tries to evade from a bad position next to the edge). Maybe add some other cards too, so that one can make a deck to use, with different combinations.
