CheatCC says: "Avalon Code is definitely one of the most promising RPGs for 2009. With some really clever puzzle mechanics and a ridiculous amount of customization for battling and defeating foes, this should be a very deep, rewarding title."
A fun, new, interesting experience that separates itself nicely from the rest of the crowd with the use of the Book of Prophecy. If you are looking for something to play at the moment, Avalon Code is definitely worth some attention. It's a little slow to start, but it soon picks up into an exciting experience. Matrix have tried something different, and managed to pull it off with smooth execution.
GameKult: Once is not custom, the beginning of Avalon Code starts with the end. The end of the world, of course, since RPG is not Japanese as the planet is not in danger.
Nintendo Life writes: "Role playing games are rapidly becoming a staple genre for the Nintendo DS, with more and more quality titles arriving on the handheld. With Final Fantasy games, Dragon Quest releases and even new titles in the form of Nostalgia and Sands of Destruction, there is a lot of competition among a crowded market so Avalon Code needs something special in order to stand out. While it has an original idea and is quite charming, key gameplay faults prevent it from riding amongst the best of the genre."
