First of all, really nice game! It has a lot of potential.
I like how you teach the workers actions by doing it yourself but I'd rather prefer a proper menu for creating, viewing and editing action chains. I have trouble keeping track of the robots (custom colors, names and labels would help) and it seems more complex actions are impossible at the moment (carrying more than one tool from one place to another or supplying more than one workbench with materials).
I'm looking forward to new versions!
