Just played the demo the moment you sent the file. The art is epic but it lacks a bit in new game play mechanics. The only new mechanic I could try out was the ice cubes, and again, it doesn't show much, it's just a block that can make bridges.
For the demo I decided to take a pretty minimal approach. I didn’t want to show too much, in case people feel satisfied enough not to try the full game. As such the demo probably isn’t that interesting for people who already played the PuzzleScript version unfortunately.
