Well, tower defense is the foundation of the game: you’re defending your office from incoming tasks and waves of clients. The typing part may or may not be implemented in the end, but it was part of the original idea, even if it eventually took a back seat.
The real game lies in managing clients and finances: the goal is to chase after the clients who pay better and faster, but of course you can only get those by surviving long days of underpaid work… just like real freelance life.
So basically, you'll be balancing income and expenses, upgrading your office to boost productivity, and cranking out more words for more clients, trying not to disappointing anyone or ending up in burnout. Easy, right? X’D
Thanks for your comment, I'm glad to hear you found it fun anyway!
