About The Donnerwald Experiment

An endless nightmare awaits Johanna Prokuri!

She was once a prodigy, capable of creating powerful automatons and other machines.
But three years ago, she lost her creativity during a nightmare.

One day a charming mole named Montgomery appears in her dreams.
He warns her that a Dream Demon "cursed" her with something known as the Mare Noctem.
The loss of her creativity is just one of the symptoms and she's about to turn into a monster soon.

Now the duo is hunting Dream Demons together and try to find a way to get rid of her curse before it's too late.

An interactive combat system with action commands. Aim with your skills and evade enemy attacks.

Dogs which can be pet.
