The full version will likely still be another 1.5-2 years from now.
As of v0.8 (The build we are working on right now), the game is about half way done (just under, I'd say).
It has 8 levels out of the 16 planned, and 17 animated Hscenes out of the 40 (or so?) planned.
Each build (1 level, 2-3Hscenes,additional mechanics/features) takes 2 months with our current workflow.
These are rough estimates obviously, but it should at least give an idea.
