I built this a year or so ago, as my Hello World to learn Corona from. It never really got anywhere, most likely because we didn’t do a great deal of marketing at the time and initially the game was a paid download which we now know was a stupid approach, but I’ve just spontaneously picked it back up to play with and actually, it’s not the terrible first-attempt I remembered it to be!
So, just because it’s made in Corona and hopefully kinda fun:
