AAAAA. What do I DO? The plan was to keep gradually building up the game, and start charging once people started donating. That hasn't happened yet. Zero donations. But now somebody put my game on the front page! It's listed among Most Popular in its genre tag! I did an update with two new turret types but that's hardly enough to justify going from $0 to $2. But if I don't switch it over now, I'll miss out on the biggest traffic spike ever. Or is that just a misconception on my part and if it were on the front page at $2 right now, nobody would be downloading it?
Should I start charging early? (AKA Oh god why is my public beta on the front page already?)
On the homepage, the fresh games section has to do with a human tagging your game to be a candidate. If you release any big updates then post again on release announcements and it may make it up there again. The other browse pages are sorted by an algorithm and there you can climb up.
