The intro is very well done and I like the sounds when the characters speak. I'm not a fan of the combat. Having the characters and enemies split in many instances makes the combats a little too overwhelming. I could go straight to the door with an X on it and break it. I'm not sure if it was the intended solution. So overall, I'd say the presentation is very good, but the gameplay would need some polish. The puzzles are simple but fun. I didn't find the one with many walls of different colors you put in the screenshots though.
