That was really fun ! There are some bugs, but overall you did a great job !
There are some bugs however, like the ultimate of the bird that is canceled if you are just next to your opponent, but still that is good. At least, it can prove that the circle shape is the weakest of the three x)
Also, there is still the bug in the character selection, but during the second playtrough. Somehow, it's impossible to lock the second character during a rematch ...
Anyways, that was great ! good job :)
