March is the deadline for the FIRST release of the game, for supporters. It will include the boar portion in Haven, one of two paths in the main adventure, and the good and ordinary "bad" end, much like GT's initial release. This is the smallest "paring down" of the game I consider worth releasing, as it is "complete" enough to be finishable end to end.
Subsequent "Content Packs" (free to anyone who's already bought the game, basically in-place upgrades) will eventually add: Hyenas in Haven, dating Scratch, the second path in the main story, the slut mode end (or something similar), and probably some other stuff.
