So, I figured out the patterns for the code locks. But then it just gets vile. I'm fine with drawing amogus for the 50th time, I figured out how to rotate the valves, and after speedrunning through all that I only have 1 section of O2 gauge left for the labyrinth section, and I don't really have any time left to navigate it and find the exit.
Maybe it's just a skill issue, but I didn't have the perseverance to finish the game, I rage quit at my 5th attempt at passing the labyrinth in the ducts.
But there's a lot of great stuff in this game: it looks really nice, environment is chunky and nicely textured, there's some good lighting. Really like how displays look, with static and all that.
Interface design is great, and main menu looks top notch.
