Nice game, it can be seen that you put a lot of detail into it with music and the powers. At first I didn't realize that you could win the game by capturing the player, so I just played for score, but then I came back and finished it!
It would have been nice to have some time to learn the controls before the fight begins. First thing that happened was I tried to move with the wrong controls and lost before I had time to react ahah.
Anyway, great work. Nice game!
