What's the different between the normal version and the cracked?
Content-wise it's the same. The normal one needs a password to play provided by the dev on Patreon. The crack removes that. The dev usually releases the game here monthly for free and removes the need for a password but it's a version behind the latest one. Latest version is for Patreons. Although that doesn't stop leakers from sharing the latest one.

extras patch only available for Mega ($15) and VIP ($25) tier. If the leaker is in that tier, sometimes they provide it.
