- You must reach a level before being able to select it in level select.
- Decafesoft copyright added to title screen.
- Fullscreen toggle (Alt + Enter) no longer results in an improperly scaled screen in windowed mode.
- Streak is now recorded as part of high score, and can be viewed in the high score menu.
- Added screen smoothing setting in screen settings.
- High Score animation has been tweaked.
