Onyx v2.0.1, or remastered, or something by Samuelstangerous - Adult Sex Game

You start the game having just lost your father. A loud crash outside leads you to a strange gem which takes you to an unfamiliar cave. Once inside, you meet your first enemy who's determined to "feed" on you. With the cave entrance lost, you have no choice but to push forward and confront the enemies within.

This game is only partially complete. My current plan is to make a series of smaller games after I finish this one.
