I cleared most of the game. (I think. I saw all but the last doohickey on your tier list.) I thought it was really cool. There was a strong feeling of escalating complexity where the next stage opens up and you think "Dang how do I do all of this at once?"
I thought the visuals were overall quite charming, but some of the modules don't look super cohesive when placed next to each other.
Here is my tier list.
