Had a play of your game in this video here - at 42:10 -, where I give my thoughts while I play. Hopefully it's helpful feedback.
This game made me feel dumb, but then smart again once I figured things out. All the puzzles made sense and it was great being able to sit down, look at the level and have that moment where you've figured out what to do. Great design and use of simple mechanics to make a good collection of brain teasers.
If you have time I'd greatly appreciate it if you could give my game a go to, happy jamming.
