Okay, first of I'd like to tell that I played alot of puzzles and such. But there was never a game that made me so mad.
The puzzles weren't really logical (especially the number puzzle on the second map) and some other parts were just weird as hell and felt like they weren't made by humans, but rather by an complete A.I.

The controls are very weird and you can't even adjust the sensitivity (R.I.P folks with high DPI).
And then there is the performance side... it was just terrible. I have an complete high-end pc (Playing new-gen games like horizon with 120+ fps) and I only managed to get about 30FPS after turning EVERYTHING to low.

So let's wrap this up:
Even for an early-access game this was an absolute disaster. It felt like somebody just thought to give A.I the prompt to make an game without having any idea how to make an game.

Definetly CANNOT recommend it.
