Well, I have already said it a couple of times in this jam, I am a sucker for neon! And to actually take us into a Tron-like environment, I just love it! Other than that, the puzzle mechanics are very interesting as well. Solid, for me one of the top. Add a death counter... Jumped off too many times :-)
Btw, I also liked the music and how it did change based on the dimension, like playing backwards or something :-)
