The on screen gui aren't buttons, just guides for what buttons do what (underlined button is the shortcut key)
Sorry about the confusion, we've updated the controls section to clarify things:
- WASD + Mouse for freelook camera
- Q + E for camera up and down
- B to begin a day
- P to open the gift shop unlock store
- U to open the park upgrades store
- M to close menus
- F to Fast forward
- Y to Skip Day
Thanks for the feedback!
