Since "free downloads" often attract a wide pool of testers, build an automated bug-reporting feature.
: Ensure that progress made in the free version is stored in a universal directory (e.g., %AppData%/Lemma/Saves ) so it carries over immediately if the user upgrades.
If the "free download" is a demo or a limited version of Lemma, develop a feature that tracks progress and unlocks.
: Add a hotkey (e.g., F12) that captures a screenshot, the player's coordinates in the world, and system logs, then uploads them to your server.
: The installer verifies the user's OS and hardware specs before pulling the full game files to ensure compatibility.
