Even if I get someone to handle the marketing, there'll still be plenty of really annoying/stressful stuff, such as setting up a company, handling payments, answering to player criticism/refund requests, reporting everything I earn so that I can be taxed accordingly etc. Not to mention that I know from experience that Multimedia Fusion 2 games tend not to work for some people due to reasons unfathomable. Publishing a game commercially while simultaneously knowing that there'll be a certain amount of customers who I can't help at all would feel somewhat wrong to me, too.
Anyway, thanks for the encouragement and compliments, guys! It's cool to know there'll be players for the game once it's done. I'll probably get the current area done sometime soon, only ~3 rooms to go!
