We plan on adding music later on! There was no time for the jam unfortunately haha.
Not sure about the checkpoint thing, but we're analyzing feedback and we're gonna try to adjust the ghost phase difficulty a bit. Also right now enemy ghost can appear at your face (which was not intended and has to be corrected).
We're both on research projects at our uni so we don't know when we will be able to add things. But we plan to!
Thank you for playing :)
