Before you start
- A Windows PC. The page warns that versions 2.1.5 and higher need DirectX 9 to avoid visual errors or crashes.
- Tolerance for beta software: the authors state the game is still a beta with known issues.
- No purchase is required for the base download on the checked page.
Find the right starting point
- Open the Boll Team’s itch.io page and read the current version notes and DirectX warning.
- Download only from that page; the authors also publish the source code on GitHub and accept contributions.
- Scan any download with your normal security software before running it.
