Its 3D models in a 2D environment and setup. I plan on doing some design documents and then hiring some artists out to do the important models (i.e. ark, defense system, animals, etc.) since I'm not good at 3D design. I'll probably be able to manage the simpler models my self however such as the asteroids and planet surface.
And I'm honestly not a big fan of the banner ads and lite/pro version for revenue. I think they're annoying and take up valuable space on a already tiny screen. If you've ever played Crossy Road or Eggs, Inc. they have a system where you can watch a short ad for a reward in the game, and from what I have played its much less annoying and actually offers the player something in return. Of course I'm trying to figure out what I could actually give players in response to watching the ads.
