We just updated the Demo to version .9914, with the following changes:
- ESC or P to toggle pause+options in game
- 2-column layout for upgrade history
- prev/next buttons for rewards list
- minimum windowed size becomes 720x720 on smaller screens
- quick restart option on game over screen
- reduced strobing mode in display options
- rare bug fix: UI freeze when closing UIs while they're still transitioning in
