So far pretty cool ideas! Hope you get some slicker menus with the final version though, and numbers for the quiz (so you know that's what you press to answer), maybe some faster speed with drops so you can actually pickup all, some highscores or similar for all games as incentive to keep playing (though as a school project understand that might not be relevant). Functionally it's great, but some more visual effects would be nice too to really make it fun to play.
