A great game with a great concept and a fine execution.
I love thinking my way through an upgrade system, but this game made it a bit too easy. The gameplay is a bit wonky, so I'll give it 4 stars. It could be better, but it's a great game!
It takes forever to get a third worker slot. I wish I could give the main character a day off, so I can have three real craftsmen working before hitting level 40.
