Really interesting idea. The gameplay is not bad but it is severely lacking in juice. I can't even tell when things get hit really. Just some simple particle effects on hit could have completely fixed that problem. I was pretty confused about the birds. I'm pretty sure this is some sort of glitch but for me the browser and windows versions of the game both were completely without audio of any kind. Yet there are credits for who did the audio so maybe thats just me. The game is not unfun, I liked it for the short time I played but it definitely needs more polish. Its really good for a jam of this length though. Good job!
