Wow this is an awesome concept. Really loved the variety in situations and how each strategy reacts and it feels quite natural. Would really love to see this polished and expanded upon.
I got as far as 'The Deep' a couple of times but each time the screen doesn't light back up when I enter that level. This also happened once when I started a fresh run, you might want to take a look at this. (You can still play, but it's all pitch dark and you can't really navigate).
Awesome idea!
