very fun game and visually obvious mechanics!
i really like the concept of your game, i haven't come across it yet, though admittedly i don't play many such games
unfortunately while playing, the game froze in this state
at least that's what i thought happened, after some further playing i realised that it didn't actually freeze, but the die for some reason didn't want to jump whenever it encountered a platform at that angle, it just stayed there.
this happened multiple times, but moving it made it jump up from the block again.
i like how your game doesn't lack anything you could put on a checklist.
the visuals are there, the sound effects are there, the music is there, the gameplay is there.
your game could use some background art (thought it may or may not be a bit distracting from the level), and i'd rate the music an ok
but other than that
great job!
