Maybe I got 11% or so of the food. Not really enough to see the theme. (Reads explanation) oh, losing sends you back, so that's how it was there and back. Kinda guessing you came up with that to save time, but a creative way to do that, so that's great! And the music is good (sounds fun, and having a wind instrument fits the character being a ghost somehow), I would have liked a sound effect when the ghost gets sent back to the beginning (but at least there is one for picking up food, and I wanted to pick them up on beat because of that). I could also have wanted to, when I get sent back to the beginning, have a moment to see what my score was.
Could have wanted to be told there was double-jumping, but I guess the level design made me realize that soon enough. (That's the kind of thing I would ideally want to let players try and figure out by themselves, but have a hint on a timer, so if they get stuck the game could tell them that... but as someone who wanted to have a spoken credits screen went with a text-only one because it was only one hour before the deadline, I can understand if that sort of stuff is missing.
I played it for a while before realizing almost everything in it is black-and-white. Well, it doesn't really need more colours, and those colours are used well. I like the animation of the ghost.
Good job everyone!
