Thanks so much for the positive feedback folks! Great to hear...
To answer a few questions:
- There's more coming, and we're hard at work on the full version. Not sure yet if there will be an intermediate demo before then, but I'll post on the site as soon as anything is available.
- Meta, a little insider secret: for fine-tune control over the speed of the game, hold down [ctrl] and use the mouse wheel. (it's not really necessary for any of the demo levels, so there isn't any instruction about it, but it's already available.)
- It's true, some of the demo levels are quite easy. But... it's a demo! The full version will have levels to definitely challenge *all* players.
- Multi-player: that's probably the #1 feature we'd love to add, but which probably won't make it into the full PC game. (It would require a major architectural rewrite of the code.) But you gotta leave something for a console version!
