I really like your game! It's simple, cute and fun. I'd personally like to use wsda or arrow keys to control the alien. My high score so far is 2010. This is the only game I haven't uninstalled from the jam!
Thanks for your comment! It made me very happy. Arrow key controls sound interesting. Maybe one of these days I'll make a game with similar mechanics but using the arrow keys instead. I think it'll be more challenging to play than with the mouse.
