This is a very solid jam game! I would have liked some sound effects, and maybe slightly more careful level layouts (since I'm not sure at times whether I'm unable to take the most straightforward route because it's part of the challenge, or because one of the blocks is just a smidge too high to jump comfortably), but those are fairly minor quibbles. I'd also quite like the "switch" blocks to be visually distinguishable from the others once those are activated, though again the memory challenge element of this might be intentional. I'm inclined to give it the benefit of the doubt. All in all, a nice little experience!
