Marth, you have to stop, your movement too low, your map designs too dependent on you running around everywhere, your stats nerfed from the first game enough to make it so you can't handle yourself easily in combat anymore, they'll kill you.
(First Fire Emblem game that feels genuinely enjoyable to play on a moment-to-moment basis, but the story is all overly long exposition dumps, the Marth reliance is particularly annoying in the remake of the original game, and there are just a variety of QoL things this game doesn't have that are actually sort of unusual for 1994, a point at which other JRPGs were getting pretty polished).
