A pointless demo
You shouldn't have submitted this as it isn't the finished version and I feel that demos/trailers don't deserve to be submitted to Newgrounds as they are not the finished version, you should wait until you finish something before deciding to submit it.
You only had two options, you could either use the dynamite or a ball of wool with the cat, it was kinda funny that you could kill the cat with the ball of wool, but this was completely pointless, as there wasn't really anything you could do, just yet another entirely pointless demo i guess. It could have used some sound as apart from in the intro there wasn't any, it seemed kinda weird having music in the intro but none in the game.
