It is something I considered implementing, and may still yet do, because I agree it could be interesting, but for this first demo I would have had to refactor things significantly for it to work. So perhaps for the future.
I always like to see procedural generation in games, so that was nice. The camera was in a little tight for my taste given the darkness and light orb mechanic. Pulling it out would allow me to use them to navigate a little better. A fun time though, good work.
