Look'at'him go, he's so precious! =D
It seems like I'm far from the only one with this issue, but I have to say it: you can become stuck pretty easily in a corner.
Trainers should become temporarily intangible after a capture attempt (when they freeze and change color), to let you have a chance at freedom ^^
Apart from that, the concept is fun: I liked the dodgeball approch to reverse-pokemon.
Good job! =)
