Red's Kingdom

Nuts are the currency - scattered everywhere and dropped by enemies and pots. 100 comes almost immediately; just play.

Story item - you're handed the medallion as you progress the main quest. Unmissable, no detour needed.

Collectables sit off the main path in most areas. Grab your first and this pops - poke around the edges of each screen.

Cumulative - 500 nuts total. Keep smashing pots and beating enemies; it stacks across the game.

Cumulative - five collectables found. They hide in side rooms and behind puzzles; sweep each area as you pass through.

A story-gated traversal item - you receive the Wing Suit as the main quest opens up new areas. Unmissable.

Raise your health to five hearts - collect heart upgrades as you explore. Comes with normal progress.

A specific collectible - find the Glowing Mushroom tucked away in its area. Explore off-path to grab it.

Cumulative - 1000 nuts all told. The long-tail currency grind; a full playthrough clears it easily.

Finish the main story - rescue Red's dad and see off King Mac. The base completion.

Track down the hidden Golden Nut in the Solas Cala area (the free update world). Explore it fully to turn it up.

Find the Golden Nut hidden in "The Golden Nut" (the area/shop of that name). Search it thoroughly.

Lock your Golden Nuts away in the vault - a story beat in the v1.3 content, once you've gathered them.

Finish the whole game without dying once. It's a gentle puzzle game so you can take your time - a careful run, ideally once you know the layouts, does it.
