The price is still too low. I can undestand not putting an absurd price the first day, as no one woudl buy it, but now he should increase it. Even more so if you plan to give real world rewards from playing the game.
Author-san will you give the ability For people to actually gain powers from the games they play? Or for them to make money off the games like some Famous Novel MMOrpg's? like "The legendary moonlight sculptor"?
