I love this so much! Good to see a fellow job sim creator too. Took a bit of time to get to know what to do, bu the game is very nice, extremely good art style, gameplay is very innovative (Don't that's how printing works but I digress ;P), and the difficulty increases quite a lot, especially during the late game too. I struggled not on the 10th level but the 9th the most, interestingly.
Anyway, for some criticism, I'd say the game is a bit on the slow side, and pairing with the fact that doing a proof print takes so much time it really adds to the the frustration of a failed attempt. (I guess that might be intended though)paired
Anyway, this is a very nicely done game in my opinion. Well done!
