Interview with the developer of space sim "Helium Rain".
"“Pleasantly surprised by the Linux sales! We knew Linux gamers were supportive of games made available to them, we didn't think we would sell many Linux copies. But we actually sold 11% of all copies on Linux".
On the question "who are looking to do a Linux version of their game, any words of advice?" - "the most important advice would be to actually release your game on Linux. Do it!”
