It's GBA Fire Emblem designed by people who don't understand GBA Fire Emblem. Also, please note that I don't mean this as an attack against the developers; I sincerely hope they improve for their next effort, and don't mean to demean them as people. For the sake of an honest review though... I have to say that I can't recommend this game.
Dark Deity is a playable game, but there are much better indie SRPGs to check out.
