Strawberry Medal

Strawberries are purely optional bragging-rights collectibles - they unlock nothing mechanical - and there are 175+ across the game, so 80 is well under half. Grab them as you explore. The key rule: a berry only counts once you land safely / finish the room after touching it, so if you die before touching solid ground it doesn't bank. Winged berries fly off if you go down, so nab those on the way up.
