I have a problem playing games with no clear ending. Does this game have one of those or is it sort of open ended like a roguelike or whatever.

There is an eventual goal, and you can succeed at it or not but it doesn't end the game.

@czarpyotr: Just gonna point out that roguelikes do generally have a clear ending goal for each play through. That said, it wouldn't be a harvest moon-esque game if you couldn't go past the narrative goal and essentially play forever.

It has an eventual story progression end. That being said it is an open ended farming rpg similar to Harvest Moon
