We got the team back together and did a spiritual successor, Marble It Up!. If you are still enjoying the original I’d recommend checking it out (on consoles and Steam).
I have many fond memories playing Marble Blast on a G5 iMac as a teen, I think it came to our Internet-less house bundled with the iMac along with Glider Pro which I think came via CD.
I managed to get Marble Blast ultra running on my Steam deck, but the controls weren't amazing. Marble It Up runs like a top, and scratches that itch I have for the original.
Fun fact: if you still have a physical Xbox 360 and previously purchased the game, you can still download it and play it.
Of course I might not have gone through the trouble if I knew about these ports, but at least I got a new hobby out of it.

I believe this is a reverse engineered port based on the Xbox 360 version.
I play it on my steamdeck once in a while. I like having native controller support now that I’m getting older.
