Nice idea and I liked the tutorial. Not very polished but in a few days it was not possible to do more. Among the games of the jam, I think that this is one with the most potential. 

As an automation enjoyer I liked the idea and was eager to try your game!

I only saw one “challenge” level present. I think more would be fun even if they are not really challenging the player.

Some bugs/unintended behavior:

• You can place several blocks on the same block. That means you can place conveyor belts on the “walls” and they work fine.
• The “final score” keeps increasing after the timer is over.
• I couldn’t get a jump pad to work, but that’s probably on me being lazy after I discovered you can place everything on top of everything.
