As promised last week, Bryan Lunduke has released his Linux distribution sim Linux Tycoon and retro space adventure title 2299: The Game as free, open-source software.

Lunduke notes that the release was made possible by a community contribution of $4,000, supporting his move to full-time, open-source development.

"I owe a big, hearty thanks to everyone who has contributed over the last week," Lunduke writes. "You have helped to show the world that it is completely viable [and practical] for a closed source indie developer to go Open Source and be funded via contributions. This is a big step."

Both games are available for Windows, Mac, and Linux.
