Pretty fun game! I liked the open level design and going through the level with two different characters was pretty creative.
I did notice that enemy hitboxes linger while they're dying, sometimes I would lose HP because I walked into a dying ghost. I also felt like the ghost's hitboxes might have been a bit bigger than their sprite.
I also would've liked to see some feedback upon taking damage, even if it is as simple as the player flashing red. Sometimes it's not noticeable until I died.
Great job overall on finishing it within the time limit!
