This is neat! The digital wireframe neon aesthetic looks great and cohesive, and the music was groovy!
I like the idea of adding some hostiles to a Portal-style first person test chamber, and it was awesome to discover how polarity interacts with enemies. This was a really cool take on the theme, and it really seems like you went out of your way to make something unique.
I do wish the levels were a little more compact - you need to walk a LONG way just to find the locations of the enemies, blocks, pressure pads and doors. It felt like I was spending more time in transit than I was actually solving puzzles.
