Another Castle combines classic platforming gameplay with the randomness of a rouguelike. You play as Andy, a dude who's looking for a random item, whether it be a kick ass magical sword, a wizard hat, or royalty. To find the item you must run, jump, and fight your way through a randomly generated castle. When you beat the game, you sadly won't get the item, as it's always in another castle. Instead, the item is now unlocked and can be found in future playthroughs of the game.
Another Castle is currently in alpha and is available for Windows, Mac, Linux, and Android. The alpha will be receiving regular updates until the 1.0 release of the game for the Wii U, Windows, Mac, Linux, iOS, Android, and OUYA later this year. Here are my most immediate goals to add to the alpha, although they are subject to change:
