Oh man, this is exactly my sort of puzzle game. I love the working out how each new mechanic works, and the ease at which you can restart levels means you can experiment with ease.
Love the general vibe, both the sound effects and music mesh well for a relaxing puzzle-solving experience.
I'd prefer if the puzzle configuration didn't reset whenever I reset the puzzle, so I can iterate on my solving process without having to set-up my last solution again!
