I figured it out. I got past level 1 and 2 and then skipped to level 20. So wow! Such a simple concept but incredible game play! There is so much you can do with just a few options. First I'd like to suggest that you have a way to turn "off" the second switch which I believe doubles the speed of progression. Also the horror aspect really got me lol. I was tense the whole time trying to figure out what the reds would do to me. Luckily (as I am not a fan of horror) they weren't terrifying so much as looming dark figures... although I imagine the rules of this Game Jam prevented you from doing much more than you did.
I thought about it some but am torn on the hallways... because of positioning, one part of me wants them labeled above the hallway but another part of me likes that you need to figure that out to avoid the enemies. It does get confusing when you are stressed though.
Either way... great job!
