Really cool idea! I liked the fact that creating a larger machines weren't always better because you have to deal with the pieces that fall off. This meant there were a lot more interesting ways you could play the game.
I wish there was a way to keep previous build though because then I'd be able to try out the best option for each playstyle much more quickly though I do understand why you'd want to prioritize other things. This feature would have kept me in my flow state for a lot longer.
Awesome ui, definitely noticed the polish. Really cool intro/splash screen and the sfx with the Godot eyes blinking were surprisingly nice. Unique restart button that tied into the world nicely.
Great game!
