This is absolute trash. Third fight is completely impossible, you're dead in three turns, tops. You can't get more joints after you lose the three, so there's no way to recover that.
Games with softlocks like that are a sign of a developer who has no idea what the fuck he's doing. This is a lazy patreon cash grab.
I am sorry that was your experience.
I tried to avoid this kind of soft locks.
Have you changed your techniques at the wingman?
If you have the basic techniques you should be able to win all the fights without the need of joints.
Did you win the fight against Demona? She will give you a better technique to make it easier.
I may "not know what I am doing", I don't consider myself a great developer or anything like that, but this is hardly a cash grab, as I have lose money till now and I am doing it out of passion for porn and games.
Remember this is a really early release.
The 0.6 version (that will be publicity released in a month approximately) has a way to make money and buy more joints if you need to.
Regardless, this is a list of the scenes in 0.5:
-Dream at the beginning
-Pinky in the lab
-Demona at her house
-Lizzy at the DrugCenter
-Scientist 1, 2 and 3
-Eva
So you may be missing a single scene for this release.
Again I am sorry you didn't like the game.
