Thanks for playing. Glad you liked it.
In the end, we just ran out of time (it's a student project).
We did this for gamepad and implemented keyboard and mouse quickly just before releasing it.
There is a control scheme in the main menu and right here in the screenshot section with the keyboard controls.
there is also a gamma setting in the main menu.
its not implemented very well but maybe it helps a little.
there just wasn't enough time...
but thanks again for playing and for your feedback.
best, Volkmar
