Game looks decent, but the character had black legs just like a big chunk of the background, so it looks a lot like a floating cube.
The RNG element with the dice doesn't complement the game in any way, the mechanic was thrown in without any real reason except meet the theme requirements.
Implementing fall damage made the gameplay slower and less fun.
Still, good job on your game!
I'll just clarify: the dice are expected to not complement the game. You gain -3 to +3 HP, so this can save your life and spare you a few minutes, or it could do the exact opposite and cause you to die (in-game). And since there are so many in one level, and you have only 10 HP, this plays quite a role in the game. For the floating legs: Yes, I was planning to add a white border to the character, but I guess I prioritized things over others.
