Great game with really neat mechanics!
As some others have said, having the shoot bubble bound differently (like to mouse) would have been better, but it's not too bad.
I really liked the idea of using the bubbles for platforming and attacking. I was especially hyped when I got the teleport ability. I even went back to just teleport around for a while.
I would love to see where you could take this if you continue it! Great job!
