For a demo, Dreamscaper is very polished. If I didn't know any better, I would think this was already a small finished release.
Gameplay-wise, it's a nice take on the roguelite genre. The concept of the game is a great choice. Peering into the mind of a teenager dealing with depression, fighting her inner demons and mental issues in the dreamworld hits home to me personally. As someone who deals with depression, anxiety, and other mental issues, I used (and still use) video games and fantasy as a protection and therapy mechanism.
Graphically, I dig the style; simple, yet effective. The tutorial threw me off a bit, as I was not a fan of the pixellated 3D style. But, once the main game kicked in, I was sold. Keeping the main character faceless was a very good choice, if intentional, given the concept of the game.
The controls are fluid. The flashing combo multiplier mechanic is a mixed bag for me. For the ranged attacks, it makes perfect sense and plays wonderfully. On melee attacks, however, I never could get the hang of pulling it off.
The star of the game thus far is easily the soundtrack. Once I got past the intro, I was hit in the face with some of the best music I've heard playing games all year. It's a wise move releasing the OST as a Kickstarter perk. I seriously can't quit gushing over the music.
As of now, the only thing I've really got to complain about is that I had a softlock loading the second stage in the demo. After restarting the game, I had no further issues.
Superb job, and good luck with the rest of the Kickstarter campaign!
