For a demo, Unbound is a fine piece of work with a lot going on. The art style, especially for the characters, looks both inspired and unique, and is well designed overall. The world being a 2D plain while still having so much depth to the background is really nice as well. Something I really enjoy seeing. I was stumped by one of the puzzles, though it seemed optional, but this was otherwise a fun time.
Good job, devs.
