Cool idea! Reminds me of the one level in Celeste (in a good way). I thought the jump was maybe a bit floaty, but I think your implementation of the chase mechanic was perfect. Nice work, especially for only 48 hours!
I should be a bit clearer. Some of the platforms feel like they should be able to be jumped on but you don't jump high enough to reach them. It was hard to get a feel for the jump. It's not so much about realism so much as clarity for the player about the character's jump height.
