Nice little experience, reminded me a lot of Closure by Tyler Glaiel, the mechanics work well together, the graphics and music are fit and the overall mood is immersive. Good job!
Wow, never even heard of it, but my first idea was sketched (almost like Closure) dark world and colorful light world with mechanics tied to "lightbulbs". Now I have to play it not to repeat a lot while working on full version:)
