So, if you haven't heard by now, Magical Diary is out on Steam.
If you bought it from me directly and want a Steam key to add the game to your library, forward your email receipt to my support address. The achievements you've already earned in-game should automatically unlock when you launch the Steam version if you install it to the same computer you were using before.
If you haven't already bought it... what are you waiting for? Limited-time discount GO GO GO.
