Not Bad
For a collab its not bad at all, and you even got it to stick with the Halloween theme too. The music and different veriety of games is decent. Would have liked it more if someone could maybe contribute some sort of brain teaser game, or something that tests people intellectually, like a memory game or even a puzzle game just so you would have something for everyone. Also it would be nice if there was a mutiplayer game, like having 2players using the same keyboard to compete against each other. I agree graphics could be better, and some games don't seem to be in sync with its function. (the ascending game, hang-time for character seems way too long, or the rate of the floor rising is too quick. Had hard time just getting past 15 ft, or maybe I just suck at that one, lol)
