In the [Development] branch, there's a preview/work in progress build with the following content added:
- Achievements!
- Control support!
- Menu updates
- Minor bug fixes
So if you want to start hunting those achievements, it's only possible in the [Development] branch at the moment. The 0.15.0 version will be available in the normal branch soon(tm).
There are still a few minor issues that I'll address in the [Development] branch, but it's stable.
Cheers,
