Just played through the game, and I LOVED it! Some parts of it are very reminiscent of Limbo and Inside, and a really enjoyed that. The puzzles and mechanics grew increasingly more interesting and difficult throughout the demo, but never once felt tired or boring. My favorite part was near the end when he gets the lightbulb on top of his head and he BECOMES the light. That added so many more challenges and possibilities to the gameplay. I can't wait to see and play the full game when it comes out!
