I liked the system where you weren’t allowed to mess with the physics once the run had started. Also found all the easter eggs for previous themes :)
The game felt less like building rube goldberg machines and more like guiding a rolling ball down a path. I feel like the dominoes were a good start but would’ve liked to see more interesting pieces to use.
The rotation controls took a little getting used to, I feel like mouse control and the scroll wheel would have been more intuitive.
It was also way too long for a jam game, I don’t think many people are going to finish this one.
