Hi! Thanks for playing and leaving a comment!
There are sort of "cheats" in the game already that I use for development and testing. Edit the settings.ini in a text editor and add a line:
debug=true
And then there's going to be a debug menu in the game that has some cheats for you to play with. There isn't much point to continue beyond the stopping point in the demo though, because you'll run out of progressing features at about that point anyway.
