I’ve finally finished the desert level. Well, kind of. It’s good enough to let me add it to the settings menu so that I can get its main functions essentially completed. I’ll still have to create an option to unlock the various characters and map types (plus add more choices to both) but that can happen at a later date <cough>Any reason to avoid making more models</cough>.
I’m now looking into integrating IAP (In App Purchases) into the game. Unfortunately I may have to ditch that idea as opening up a merchant account (often quite expensive) is WAY farther than I wish to go. It’s possibly something to look at in the future but for such a simple game as this one (and one that I doubt will generate much revenue) it’s simply too much to bother with. Perhaps just keep the game Play/Watch Ads to unlock items and see how well that goes.
