This was a fun little game that fits the them well! The movement feels very weighty, but not in a bad way whatsoever. It adds tension for every jump you make, which was nice! I found myself failing a few times, but it didn't matter because the levels were short enough to make a loss of progress not that big of a deal! I wish there was a bit of consistency with what was considered a hazard and what was not (find it weird that running into the ghost doesn't kill you and win the game). Maybe if given enough time, you could have made the ghosts grab the player if the player collides with the ghost's hitbox and drag you all the way to the beginning of the level! I also like the use of the art and music assets! Wish there were more sound effects for stuff like when you die.
All in all, I had fun with this! I really wish there were more levels! I can see this game offering a lot of neat puzzle and platforming segments, which would be really fun! I hope you had fun with the jam! Great work!
