Took me some time to understand how the game worked:
1. for some reason WASD didn't work (for the first 2 puzzles)
2. I got confused because space did not do anything initially.
It is a good take on adding puzzles, using the dice faces as the level base and dice dots as platforms.
Unfortunately it got hard for me when the changing platforms were introduced.
I had fun :)
If you have some free time, please take a look at my submission and provide some feedback (as I am considering it for expansion as a PC game)
