Adult PC Game: BEngel Ver.1.3 by Pridedrawin Win/Linux Archive

You play Ben, an angel sent from heaven to become the guardian angel of Tim, a typical young man on Earth.
You are supposed to guide him, without him knowing you are even there.
Unfortunately, the moment you contact him, he immediately becomes aware of your presence.
Even worse, though, while you can sense his feelings and thoughts, you cannot “direct” him in the slightest.
He very much has his own mind, leaving you with an almost impossible task.​
