Demo update

As development of the full game has been ongoing, fixes, updates and improvements have been made to many areas. As some affect the content available in the demo, it seemed like a good idea to release a new version of the demo.

In particular the game controller support got many improvements. See the Gamepads, gamepads & gamepads blog for details.

Player jumping has been improved to be more predictable and reliable.

The tutorial for how to use the first power up has been re-worked to be a better integrated part of the solution for solving that particular level predicament.

Please let me know if you have any issues using a game controller to play the game. Also of interest would be to know if there are any issues using a Steam deck.
