Great first game! You had an idea, and implemented it. As far I as could tell, no serious bugs or flaws in the code either. I would recommend trying to get rid of the white boxes around the sprites (maybe they only show up in the web version) and maybe make the beaks on the birds stand out a little more to indicate they're the danger zones, but you've got a solid game here. Good work and I hope to see you again at next year's jam!
