I've honestly not played Stanley Parable before (as mentioned in all the previous comments); but this was darn enjoyable. The voice acting and comedic execution was top notch!
I did miss the initial parts of it; as i was having audio issues and didn't hear a single thing on the first few spins :( Hope you can implement a new game button. And to be able to pull up the menu to quit would have been great (unless i didn't do it correctly?)
Nevertheless, great work and i can see a lot of effort been put into this especially with the limited jam time.
