You can either be nice or mean to him, depending if you want him to be your Lover Slut or Slave Slut. As this is an unfinished game, this feature has no effect as of yet.
Gomamon Trainer is a work-in-progress visual novel digimon smut game which pushes you into a strange digital world, trapped with a cute male Gomamon. The very same Gomamon from Digimon Adventure.
This is a simple enough game. You press buttons to advance the game, talk and molest Gomamon. It is heavily inspired by My Very Own Lith and I recommend you check it out in case it is unknown to you.
This is an unfinished game and will still need many resources to be completed.
