I really like the concept! I think it would be nice for it to be more frantic, but it is a really cool idea. I got killed just after starting because a kite spawned in the same place as the UFO, but besides that really good submission!
Thanks very much :) It can be a bit easy for more advanced players, I think I'll have to add a difficulty slider! The kites spawning on you at the start is a bit of a bug, in fact the player starts with extra health because there always seems to be a collision right off the bat
