Flying enemies

The most annoying kind. 

Flying enemy A - Ghost

The original sprite was 32 x 32 so it was very nice to just have to upscale x2 and replace the original spritesheet in the atlas.
First enemy, done!

Flying enemy B - Blood Butterfly

This one was a little more tricky than the last one.

I wanted to make a traditional bat at first, and I even went so far as to align the sprite sheet, and recoloring the sprites.

However, when I tested in the engine, I noticed two things:

Flying enemy C - The Occuleye

I already knew this assets as I used it almost as it is in Midnight Pumpkins Rising, one of my previous gamejam games. This Rotating Eye Ball by codeinfernogames has been released under CC0 licence, so it was a perfect match for this project. The original sprite has 16 animation frames and I had to drastically cut it to reduce the animation to 6.
For the PlataGO! asset pack, Rotating Eyeball will only look to one side and  won't make a complete turn. However, as it is a flying enemy it will frequently change direction as it passes over the player, so I think it should be ok.
