Realm of the Ghost King is now $2.99 at full price! This doesn't change much, it just seems like a good thing to do. The game will still be on sale for around $1 every time there's a sale, so it's best to wait for a sale rather than buying it at full price.
I'll continue to support the game from both the application and online side for a while to come. Costs to run the servers that hold all the Daily Challenge data are pretty minimal and the game has mostly recouped all the costs beyond my own time spent developing it (which I don't know the value of, but it was a free time passion project). Maybe some day I'll even make a second game! Who knows?
Thanks for your support!
