I appreciate the fact that you wanted to upload something to kongregate but please no chat things. I don't want to sound like a dick but seriosly there are an abundance of chat games on this site. There are just too many
Not bad for a first game but make it easier at the beginning and then geting harder after a while. Also add tiles around the edges of the screen so you cant go off screen
