Blue Bats are best bats!

Very nice stuff you got, you have an interesting use of color

Thanks

ok, that's good to know.

tho this is already taking up the full width available for the type of spritesheet it used in

Nicely pixeled =)

I'd change one frame though: wing movements of bats (or birds) are not symmetrical when going up or down, they couldn't fly if they were! The downward move frame should have extended wings.
