This was really cool! Reminded me of a fun game called "Lovers in a Dangerous Spacetime". Found a couple bugs though:
1. The player could sometimes press buttons through the floor if the jumps were timed well enough.
2. The player could leap through the wall and out of the giant dice.
Other than those, this was really fun and fairly well designed, especially for starting a day late into the jam! Keep up the good work!
