Quick answer
Project Reignition is distributed as a downloadable fan remake rather than a Steam store release. Use the current release page, download the build for your platform, and keep the extracted folder together.
Windows
- Open the Game Jolt project page or the project’s GitHub releases.
- Download the Windows archive for the release you want to test.
- Extract the archive to a folder you control.
- Launch the included executable from the extracted folder.
Linux and Steam Deck
The project page provides a Linux build. On Steam Deck, download it in Desktop Mode, extract it, make the binary executable if required by the build, and add it as a non-Steam game. The exact Proton or compatibility-layer requirement for the current build is not confirmed.
Before troubleshooting
Keep the downloaded archive, extracted folder, and save location separate from the browser’s temporary downloads folder. If the game does not start, record the build version and operating system before trying another release.
Independent fan guide: this site does not distribute the game binaries and is not affiliated with SEGA or the Project Reignition team.
