Since I'm changing a bunch of stuff (including the graphics) I will release a second demo.
And If all goes well I will release the full version along with that demo.
I'm not really sure when exactly the second demo will be out. But when I do I'll update the game page.
The price was 3 dollars (at first), which was reasonable for a low poly niche game like this one. But now that I am upgrading the quality of the graphics, I'm thinking of raising the price to 10 dollars maximum. Again I'll update the game page when my decision is final.
