Dave Probert wrote a complete iPad game (from idea to App store submission) in just a week using Livecode. The actual approval process took longer than the time it took to write the code!
The game is HexThello - a 2 player boardgame based on the 'Reversi/Othello' type of rules, but using a hexagonal grid instead of the usual squares. This gives it an added extra two directions of action and requires a little more thought during play. The game has three modes: two player, one player, and even no player - the program plays itself.
Dave explained "LiveCode provides a medium that was quick to produce a prototype of the game, and then to enhance and develop the final working product in just a few days. The cleaning up and testing was another couple of days. For the most part it was quite a painless process. For anyone out there who is looking at creating a 2D game and wants a lot of control over the precise action, then Livecode is a good solution."
It's in the AppStore.
