I'll be the first to admit that while fun, Urth isn't the best looking of games. Nor the most optimized. In fact most of the code hasn't changed that much since it was first released during Ludum Dare. I've now set out to change that and port the whole thing to unity, while making it prettier and adding new features/levels and so on.
The port is going well, and I can get away with using the free version of unity. However I can't get it on mobile platforms because that requires an additional license. Which costs money. Which I don't have.
With that In mind I bring you the one the only "Get urth with unity on android" indiegogo campaign!
And the link to the thing itself:
