The visuals are undeniable great, but what the game really lacks is character developement. It is in fact an "early" build for a small (one man?) team, so one can still hope.
As people said before, the beginning is quite interesting, you can still trigger some stuff by changing your sisters opinion of you. But later it comes down to hit wait until the next linear scene is triggered - I cannot imagine how it would feel like to play this game without cheats :O
The old scenes also need to show some variation, e.g. Lisa sleeps naked and sucks Max's dick, but when he walks in on her dressing, she is upset ... why? After the 10th time she should either lock the door, don't care anymore or maybe even tease him. The whole interaction became too linear, there is no real interaction with the other characters and therefore the game looses its flair. I was not surprised in the last versions, you only slowly get what the first version already promised you.
When can I throw spiders into the shower again? Or when is somebody approaching Max for a change? Why are the sisters so stupid, take Alice - why does she not realize that spiders only appear when Max is around. A nice twist out of the situation could be that at some point, she agrees to tan topless when no more spiders appear in her vicinity.
Max might still need to clean the garden of spiders, but everybody would be happy
That is also why I like Olivia best, she is the only one that seems to act on her own will. Maybe mostly because she is not one of the mindless zombies you have to interact with every day.
Adding more characters is of course a way to solve the problem, but I think adding variety and depth to the existing characters would result in a much better game.
You might have thought that developers had realized why people like Akabur's games so much (appart from the grinding, you cheat anyway). But real depth and the tiny surprises probably do not increase the number of subscribers as fast.
