demo updates

- added a title track to the main menu
- also quicker access to the control map

Vilakshan's new music is so great! I am so happy to have collaborators who are so talented.
Everything about the project is moving in the right direction imho and the demo is going to really shine.
The steam release is scheduled for 7/22. I might soft launch it earlier to get some feedback, but this launch is really a soft launch as "NextFest" in October is really when people look for new demos.

So many great new games have come out recently and I want to check them out and let them influence me. It's very important that the feel of the game is still modern, but at the same time very classical. That has been the pillar from the beginning.

I mostly want to continue to work on optimizations, especially for Steam Deck. So the demo itself won't be changing much other than fine tuning, bug fixes, perf fixes, and package shrinking.,. not to say there wont be a lot of design changes too, but this is the current priorities.
