If you like to live dangerously, kick over to the Unstable branch under betas, and you'll have the latest.
It includes the following:
- Adds Daily and Weekly challenge modes
- Updates localization (everything is now localized properly)
- Adds Hardcore variants of each (these score you, and are one try per day/week ONLY... so probs practice the day or week's map a bit first)
- Fixes the Punched A Dude achievement, you should get it now
- Fixes the issue where a fresh install started with a handful of upgrades already unlocked
