SimpleQuest is an intentionally straightforward RPG in the style of early 90s jRPGs, in the vein of early 1990s-era Dragon Quest or Final Fantasy. If you have played any of those games, then it will feel familiar.
In the game, you play "Hero", a young man burdened with a stupid name. He has come to a tiny town, named Carp's Bend, in the hopes of figuring out his life.
Play time should be a few hours at most.
