Played through and found multiple things which are shown in game, but are not able to be used.
Asked the dev and they stated that this is being re-done in Unity in the new year, this Ren'Py version is basically being used as a beta/UAT.
The fact that vast majority of the game is unavailable and the decision to force players to have to play through twice - Ren'Py saves won't work with Unity version coming - is basically the dev using the community here to work as testers for this product.
That's not cool, at all.
Onto the game itself, it's poor.
There are no indicators of where you need to go, or what you need to do.
It's just an endless clickfest.
There are 6 girls, 7 counting the one who you milk - but this functionality doesn't exist yet - these 6 girls have 1 sex scene each.
You need to spend literally hours clicking to progress research, it took me over 900 in game days to reach level 4/5 on everything & that was with 2 girls also doing research for one of their two assigned tasks.
Far too much worthless grinding to get nowhere.
If you want to get RSI in your finger from clicking the mouse button so much & see only 6 scenes with any sexual content, this might be the game for you.
I would still suggest not wasting your time, as anything you accompish now will be for nothing when it moves to Unity.
It is absolutley not the the game for me. Delete.
