Bugfix
- Demo and full version were using same save files. As result, playing demo on the same computer with the full game would erase the progress.
- The problem is now fixed: Demo uses different save files now.
- Unfortunately, this fix results in progress in the demo being reset.
- Hopefully that's not a big issue, as progress in the demo is limited to 1 unlock only, plus unlocked difficulties.
- Sorry for the inconvenience. That was a mistake on my, developer's, side.
