we'll try without vr, hopefully the game isn't that slow.
It's not that the game is slow - it's that you will be slow. The people who make the VR plugin that allows this to work simulate the VR elements - so you have to move with WASD, but then there's another mode you turn on to simulate the VR hand motion, and you have to control that in two dimensions at a time. Since this game is an action/timed event game, you simply won't be able to keep up with the customers!
On the other hand, when the game ends, it doesn't throw you to a menu or anything, so you can take your time and explore how making the food works if you like.
But if you have a friend or viewer with a Vive, it remains the much better options.
