I made a level that I think is pretty hard >:) (it is possible)
https://drive.google.com/file/d/1R2LC4l1kzuZjssU2_e-u1RKSVo1080-Q/view?usp=shari...

Nice level showing off a possible mechanic that is not in the main puzzles, and requires a bit of thinking outside the box (literally)

Is it possible to make it brighter? In its current state I can barely see the level.

Edit: I just beat it, and I have to say, that was a great puzzle. I can imagine this in the challenge world of the base game (with a couple prior levels to introduce the mechanic)

Finally beat this! I definitely really enjoyed the puzzle/concept. However, I really didn't like not being able to see :(.  I would definitely prefer this level with a more easily parsable color palette.

I think there's multiple solutions? I think I skipped a few steps.

Here's a pastebin cause itch.io doesn't have spoiler text.
