This was a fun little platformer, I really liked the ghost sprites! I have a couple of suggestions for how to improve some of the gameplay:
- I think the hit-boxes for the angry ghosts were not quite right. On the right side I could overlap them quite a bit but on the left/top I seemed to get caught very easily.
- The springs only seemed to work well when you walk onto them, not when you fall on them from a height. I think you need to set the downward velocity to 0 before launching the character up, if that makes sense.
Overall though it was a really nice entry, good job!
