The Normal Ending: Big Goodbye
Clear all four towers (tutorial + Red/Green/Yellow/Blue) and the Black Obelisk door opens. Carry 6 blorbs to the Obelisk to forge the Black Key, then take it to the wall gate in the far west. Beyond the wall you walk a long distance toward the Black Sphere. The final zone switches communication off — no voice, only gestures and signals — and tests everything you've learned. Clear it and the credits roll. This is the normal ending (achievements Big Wall and Big Goodbye).
The True / 100% Ending
After the normal ending, post-game content unlocks. To reach the true ending:
- Take the Chairlift (unlocked at Green Tower) to the east-ridge challenge area. A purple door behind the east chairlift station opens.
- Complete all seven purple challenges to collect purple blorbs.
- Forge the white key from the purple blorbs.
- Return to the small black sphere back in the tutorial / map area and trigger the ending. This is the 100% true ending (achievements Big Game and Big Pack).
The Seven Purple Challenges
These are the gate to 100%. Several forbid speech, so pre-agree gestures during the main towers:
- Wait 30 Minutes House — lock yourself in and wait (easiest).
- Golf — daisy-chain a ball from the Red-section golf course to the east hole; hand-to-hand only.
- 36 Drawings — a We Were Here-style grid: one watches, one places, with precise description.
- 9 Speakers But You Can't Talk — memorise nine speaker positions and signal by gesture (widely considered hardest).
- 9 Symbols But You Can't Talk — the same gesture system, simplified.
- Platforming, But Do It Fast — a timed run with an egg timer and human-stack jumps.
- Many Lights Everywhere — one reads light positions (red only), one presses buttons, using 1-flash = yes / 2-flash = no.
Tips for the Purple Run
- Do 9 Symbols before 9 Speakers — it teaches the same gesture language at lower stakes.
- The challenge area is reach only via the chairlift, so Green Tower is effectively required first.
- Stacking (see over the wall) helps in the platforming challenge.
The normal ending is achievable by any group. The 100% route assumes you've finished the main story and are comfortable with no-communication puzzles.
