Really awesome game! I love the artwork and being able to choose your own music is a great feature.
Took me a while to understand where I could save and rewind position, but once I figured it out it was pretty obvious. Maybe adding it to the tutorial would have been good anyway. Also the maze looking level can be beaten just going between the walls sideways.
But apart from those, I was amazed with this entry and I encourage you to make a full game out of it once the jam is over. I would play it! Well done and keep it up :)
Would really appreciate if you could check out my game and leave a rating, thanks!
