so games style corpse party can enter the game jam?, I was thinking of putting exploration inside the school and small puzzles similar to those of corpse party
Corpse Party is an acceptable example of a hybrid we'd allow into the jam, yes. Some of the submissions in the past have had a component of exploration fulfilled by RPG Maker or similar tools.
We had another doubt in the team, does mad father fall into that same category? and if he doesn't, where exactly is the line that divides mad father and corpse party?
