I ended up not relying on unpaid interns at all - I just put every new hiree on marketing for most of the time, and finished the game in just 2 days. Which is a totally realistic, industry standard procedure - it's seemingly how all major publishers try to do business lately xd
I love the artstyle and the gameplay! It was very satisfying to be able to scoop all of the workers up, but that sometimes made it hard to reassign an exact amount of them to a different task. That was only a minor inconvenience though.
I lift my dev chalice to you!
