I cheesed the last two puzzles. I couldn't find out what the intentional way was.
Cube jumps basically.
I found out about the technique with R2 while holding the cube only in the last puzzle, which was probably required for the 2nd last puzzle.

This is great. Not sure if this is a bug or me misunderstanding what to do. In the puzzle with the rays of light and the yellow cube where you have to clear 2 large gaps with the jump. The jump doesn't go far enough. Any hints? Thank you

It sorta reminds me of portal great job
