I played trough it, and really loved it! I think I laughed too much, and that ending is just so PERFECT. Its definitly the best game I played trought yet. The biggest problem I had though was that I kept tabbing out of the game while trying to aim. I dont know if its my computer, unity or the game but my mouse never stayed in the game, went in my second screen and made me get hit a lot. Also, after the car factory (which I had uncovered in the first level and I was so proud thinking it was a secret lol) where to go is really unclear. I went arond until I figured out the right path.
There is also some really minor things like the fact pressing R on level 1 makes you watch the (amazing) cutscene again. But thats not too bad considering I only did it cuz I missed some of the controls. And theres a typo in the sentence "are you curious about he's doing with the button". but none of that takes away from the great experience! Great job!
