Great game! I like the concept and implementation, maybe you can consider adding some new content post-jam :) The sound design is really good too.
Would be good to also have some features improving the overall user experience, like progress saving or level selection. Now it's easy to just quit the game accidentally by pressing esc and the progress is lost.
P.S. Having to swipe the card at each gate while running away from angry ghosts was a really nice touch :)
