Many many thanks again.
Regarding the possession, there is actually a counter for it in the bottom right corner with the skull icon. Health is in the bottom left corner with the heart icon. I made them small to try and keep the HUD as clear as possible. (Maybe too small though :D)
As you mentioned though, clarity could be better for this. It should either explain this in-game or be intuitive enough to not to require it, so I will work on some improvements.
I am really glad you see some potential in it though. You know, there is actually a lot more game-time in this project in its current state, including two more endings. But so far I have not seen anyone play far enough which probably highlights the problems with it at the moment.
Anyhow, thank-you very much once again for all of your recommendations.
