This is quite simply an AMAZING jam game. I love the mechanics, the vibes, the art, the sound. It's great all around. My only real suggestion for how it could be improved is to change the sound of the door closing behind you to something different (i feel different sounds for the door in front of you (goal) and behind you (closing off previous level) would be a better experience). Some turning could also be cool, so the goal door isn't directly in a straight line for all the levels.
The main puzzle mechanic was really fun and I thoroughly enjoyed each room. In the later levels I was spending quite a few minutes trying to figure it out, and if that is the gameplay with just simple shapes + wires + moving/rotating pieces, there is so much room for expansion and more puzzle components if you wished to.
The puzzles really felt like I was crafting a solution, even though you most likely had already thought of what I was up to and crafted the levels exactly so I'd do what I did.
The vibes were great, especially with the rising tension, and the strange face at the end. The ending itself very much made me want to see more, building up the atmosphere to its highest point.
Overall, great game. Loved it
