Pretty creative concept and its fun to try and get a high score. I like timing the catches, but the slow catch speed does make the late game too dependent on the which powerups you get. Overall, good job.
Good game, but if your going to have me swap between two modes, where I can't interact with the other mode's controls when in I am in the a mode, then you don't have to use different buttons. Have to switch between the arrow keys and Q/E feels very awkward.
