Interesting gameplay and super presentation. The art is great. I thought I recognized the style, and it's indeed the Immorsona artist. Do they post their art online somewhere?
I can imagine the gameplay getting really complicated if you let Nightmares/Dreams differ even more in what attributes they give, so that the player would have to Bootstrap dreams from Nightmares carefully without turning the Nightmares needed to bootstrap other dreams into Dreams. I definitely see the potential, although right now, it's kind of easy once the player figures out how the game works.
