Fans of those absolutely insane Touhou games will probably find something to love here. Frenticpony over on Youtube has released a bunch of videos of his progress on a Ponihou game.
So far it looks like he has some Ponyville backdrops added, as well as a full on boss fight with Pinkie Pie.
This might be a fun one later on when he gets all the bugs worked out! I know a few people in particular who will be all over it.
