Oh ok I see ! And some tiles you can only turn on in some of the colors, right ?
Now I see the concept.
I will say that no matter what, repeating the same level several times will unfortunately risk being frustrating. What happened to me was I died, and then I respawned on a tile of the wrong color so I died immediately again.
With that said, good job on the game. Both platforming part feel good to play, which is impressive considering the ambitious scale of the project for a solo gamejam. I think you're taking the right lesson from this about clean design.
Tougher part imo about work in a gamejam is having a clear well defined project from the start. Because it's never like that, second tougher part is being able to kill your children and relocate your effort when it's necessary. So congrats for that and delivering on a complete game !
