Not bad at all! I really like the geometry based puzzles and the voice acting is great. I ran into an issue where the voice would cut off and start the next piece of dialogue if you beat the room too quickly and the game does not capture your cursor. On a single monitor this likely wont be an issue but with my second monitor to the right of my primary I had to turn left exclusively to prevent clicking out of the game. Some of the lighting is a bit intense as well, mostly that large orange indoor lights. Pretty solid foundation!
