Dang, this was nice! The art, music, mechanics, all of it was so good! I love balancing out combat and puzzles, I could easily play another 40hrs of this. My only two suggestions are gamepad support, and opening the door had a stronger visual effect (like an animation, maybe some dust swirls). You already have a great audio cue, but I kept expecting to have to "full up" the reactors so that's where my attention was and it took a beat to realize a path opened. Again, this is super duper minor and not hard to figure out, it's like complaining about the stitching on the napkin at a michellin star restaurant. Would love to see more of this, keep it up!
