I bought Tracks on itch.io and do not see an option to get the new Sci-Fi Pack. I see it on Steam. Is there a way to transfer my license from itch.io to Steam if that's the only way to buy the pack?
I'm afraid itch.io doesn't seem to have a nice way to support DLC of this type, I'm currently looking into how I could handle it..
All Tracks purchases from itch.io include a free Steam key, so you can use that to access the game through Steam and get the DLC if you choose to: here are some instructions.
I was able to follow your instructions and everything works as expected now on Steam. Thanks, I appreciate the help.
