It's not every day you get surprise homebrew releases like this! Anguna: Warriors of Virtue is a complete action-adventure game for the GBA, boasting five dungeons, unique enemies and bosses, and an expansive overworld. Hidden rooms, secrets, and special weapons -- bear traps, dynamite, and more -- are scattered around Aguna. It's all the work of a single programmer (with sprites provided by Chris Hildenbrand), Nathan Tolbert, who labored over the game as a hobby for the past three years.
Very much inspired by the original The Legend of Zelda, Anguna is an old-school experience that doesn't hold your hand whatsoever. Other than a few sentences to set the plot and a sword, you aren't given much to work with. After you fight your way through the introduction dungeon, you'll need to explore the overworld for a while before figuring out where to head next.
If a lifetime of easy gaming has turned you soft, the official site has a guide for getting started that should help you out. The site also offers physical GBA cartridges of the game if you'd rather not play Anguna on an emulator or off a flashcart, though pricing varies for that option.
To promote Anguna: Warriors of Virtue's release, Nathan is hosting a contest -- the first person to submit proof that they've gathered all of the game's hidden power-ups and items will receive a free cartridge of the game.
