The game looks fun, but I struggled with the controls. Everything in the brain is just linked to WASD so much that having only D makes it very hard. On the one hand, it may imitate your struggle with orientation when half-awake. On the other hand, it distracts from enjoying the game. I also discovered that when asleep, I was immune to monsters. Twice I was also able to move in that state—or, better yet, slide on the ground and kill the enemies on my way.
