Now that more of the modular components are completely functional (not polished), I've been able to add some more value to the demo via physics puzzles and the like.
You'll see a couple varieties including some fairly standard bomb puzzles as well as ball puzzles like the maze puzzle.
It's been a long time coming. A lot of UI elements are still being drawn to provide additional polish to the user interface and hopefully I'll be able to get the demo out the door. There is now a beginning and the end to the demo so technically you can play through it from start to finish but a lot of story, polish, and some additional puzzle mechanics to the boss fights still need to be put into place.
