It was just yesterday when I was trying to find Alex Swanson's contact info or some other way to ask him (and/or whoever else worked on the original Marble Blast) these questions. Then I stumbled upon the Marble Blast Wiki page for Marble Blast Gold and, to my surprise, found a screenshot of the September 2002 beta-build of Marble Blast with what appears to be an early version of Upward Spiral.

Apart from the green HUD text and the 'blah' marble texture in the game in general, I noticed the floor texture used for the level was missing its bullseye/target pattern and surrounded with yellow borders instead of purple like with the final product. The HUD itself also had differences such as the numbers being further apart from one another.
Then I found an interview with Jay Moore on The Gamers Press, and there I managed to find not only that same screenshot , but also two other pre-release screenshots, this time of what appears to be an early version of Tube Treasure:

Apart from the square-shaped (cubic?) purple 'gems', the shading with this older build appears to be different, and the Super Jump powerup is shaped like a rocket (like the Super Speed, but pointing upwards and colored orange and yellow).
Looking at the TCRF article for Marble Blast days ago, the soundsprofiles.cs file listed a couple of sounds that were presumably removed from the game: one titled 'penalty' and the other 'destroyedVoice'.
Am I the first one on this forum to have found these, or did someone else here do that before today? Is there a way to ask Mr. Swanson et al about the beta build?
Thanks in advance.
