Nice game !
Simple shapes often do the job & it can be enough fo a jam game :)
The music loop is very short & get a bit repetitive & anoying kinda fast.
The controls are fine & respond well, but the white square was a bit slippery & hard to position.
The difficulty curve of your puzzles was coherent. the last one was a bit tricky but does deliver a nice "haha" moment when you figure it out.
Your doors/moving walls looked exactly like the floor so it was not really obvious that they were interactable. maybe put them in a different color ?
Nice job :)
