Hey thank you, that means a lot to me. I used blender exclusively but I just looked up sprytile and it's actually a blender plguin and looks amazing, I wish I had found that earlier. I was contemplating to write a tool like that for unity cause I got so annoyed building the level bit by bit. The enemies are all just basic spherers modified a bit and because I didn't know how to rig and animate properly in blender, all the animations are powered by code ( y-axis squash to look like breathing ).
Really enjoyed your game by the way!
