Very good take on the theme !
Overall a relaxing experience where making contraptions is very satisfying.
That said, I find the planning and execution to be pretty tiring. The game is fun, don't get me wrong, but seeing your creation fail after 15 minutes of placing arrows and having to redo the whole thing is very devastating.
And the connector tutorial wasn't all that clear.
But all and all, very creative and clever puzzle game.
Good job !
