Greetings!
While we're working on our next update (that will include difficulty settings, bug fixes and some other things) we want to share with you our little DevBlog on Tumblr.
Here it is: http://riftygames.tumblr.com/
We are posting some not-so-official updates on our development, tips'n'tricks for other Unity developers and other funny and interesting stuff.
We'll be glad if you'll will follow us there, participate in discussions or share our posts to your friends!
