Very well polished.
Puzzle for level 12 is either super convoluted or I got super unlucky, I found that clicking the little decorative particles did something and made a buzzer, never made progress on it despite trying multiple times.
Trying to see the light coloured electricity against the light coloured tiles was a little challenging, I would like to see it tint the tile its colour. I noticed you used yellow, cyan, and magenta as the colours, which are much brighter than red, green, and blue on a screen.
I liked the theme interpretation a lot, fits perfectly.
Puzzles were pretty clever, though quite easy.
