The full game is actually available for free now! ๐
The public 1.0 release is already out, so you can download and play the complete story here:
If you'd prefer to start from a specific checkpoint instead of playing through the earlier parts again, we also have bonus codes available. These can unlock specific starting points and are also a way to support the project.
So you don't need to purchase the game to get the full experience — the complete story is available in the free version.
