Thanks! I'll hopefully have a couple more levels out on a different page (to which I'll link on the demo page) by today or tomorrow.
The UI was a rush job; I only had about ten or fifteen minutes. When I release the next version, I'll definitely touch up the UI. For the most part, the rest of the game won't hold your hand as much, but I only got as far as the tutorial level. The action prompts will be kept, though, and I will work out the placement.
