It takes about 10 in-game days to max out tits and body with the lowest intensity which is autoplay. Then you intentionally unsynch the outer stream for a bit so your cock shrinks off. Then keep playing for a bit and on day 20 or so you should get one ending. It’s a bit slower than actually playing the minigame but I honestly think it’s reasonable.
The hypnosis game and the after effects of it are integral part of the experience and I’m pretty happy with it. If you don’t have the time for the lowest intensity, I’m afraid then this might just not be for you like you said. But I do get the point of a too hard game and jacking at the same time, completely reasonable, but that’s why the lowest intensity is there.
Thanks for giving it a shot and commenting. I’ll try to keep this in mind with my future projects.
Edit: If I update this I’ll see if I tone down the default intensity
