Neat idea!

I managed to get up to level 5! just cannot make that jump at the end. The visual presentation is wonderful, you've provided a really effective contrast with the music and look of the second dimension. I did find the platforming a bit frustrating at times, the gravity feels like it's set *really* high for what's ostensibly a puzzle platformer? Flip side of that is it does feel quite satisfying when you complete a level

Two things I also wanted to ask about because I'm not quite sure if they're bugs or intentional design : A) Are spikefloors meant to still be dangerous even when wonder-ified, and B) is not being able to jump on crates intentional. I found you don't ever need to actually jump off of one for a puzzle but there's a few times they're used as elevators?

The variety of mechanics you've got for the different levels is quite impressive, and having your key mechanic be an on/off switch for them is a clever through-line. Despite my struggles, I found there's some really solid elements here. Nice work with this one 

A wonderful vibe with amazing dynamic music and vibrant visual design. The level design was also incredibly varied and made excellent use of the Wonder Radius, which was crazy cool. Level 4 was the most challenging for me, and was also the most satisfying to beat.

quite the interesting concept, you made some fun puzzles here, and i like the colors used in the wonder world. very nice.

The puzzles and movement were really fun, and the colors were weirdly relaxing and comfortable to look at.
Music was the cherry on top.
