Somninsanium was created for the YAZJam2 on itch.io in August 2021. My focus and goal in this project was to recreate a certain scene and atmosphere I had in mind, using only 3D assets. It is supposed to be experimental, again, just like Hekate, my first YAZJam project. Based on the chosen theme, the gameplay doesn't take longer than 5 minutes. So don't expect an epic story or complex gameplay.


The game is available in English only. There isn't much text anyway, so you should be able to play it even if you don't exactly understand everything.


  • Enter to start the game
  • Move your mouse to look around
  • WASD or arrow keys to walk
  • Space to jump
  • Shift to run
  • E or right click to pick up
  • ESC to Quit the game


Game Design & Development by me (Wiebke Scholz | Hexenwerk)

I recorded all sound effects by myself as well. It was the main requirement & restriction of this game jam to only use sounds based on voice during the jam.

Haha, nice little game experience! The best way I can describe it is a "sweet nightmare" if that makes sense, because it feels like a funny light hearted dream, while somehow still feeling like a disturbing nightmare.

Well done!


Thank you, CP-Dimensions. You described exactly what I was aiming for with this little game experience, so I'm happy that it works. :)


It really does give the feeling you intended then! Great work!


I've played your game 3 times and it was a lot of fun haha. I think you hold a concept similar to The Stanley Parable, which was a very successful game. Playing again to try different combinations at the end gave different results, and that was very nice to have these various possibilities.

I think it could easily become a full game and it would be quite popular with such an unusual style ^^

The sound design with your voice is very immersive, bothering (in a good way with the world), and ... it works!

I smiled at the sound of the duck on the toilet, and at the poop taking a bath. The humour really adds something to that weird place, with the scary hands that want to take you!

Graphics are cool to know, the 3d modeling and animation are clean and look good!

Overall, well done!


Thank you for your nice feedback! Developing this small game was fun and I hope I'll find the time to give it a proper ending soon.
