This is some ingenious shit.
I really enjoyed figuring out how to build and use the machine... that said, maybe a small indicator showing the 'stockroom' will help. It took me too long to figure out "just go right for spare parts".
Also, is there a way to repair or recharge components? Or is it game over when you run out of a certain part? Right now I am trying to figure out how to get another specific part that I have none of. :/
So far though, excellent! Unlike most offerings and rewards thinking. What more could you ask?! Well, I *could* ask for more 'vertical initial connecter thingies'... but ...
Cheers!
