๐ŸฆŸ CHORUS โ€” Impact Ladder

Revised Feb 20 2026 ยท Per Gin's direction: net accumulation spine + community scale ceiling

Design Philosophy

The net is the unit. Players don't unlock "bigger things" as they progress โ€” they fund more nets, building toward scale milestones that feel increasingly powerful. Early micro-interventions (water, vitamins, deworming) remain as day-one quick wins, but the main game loop is net accumulation.

Why this works: "You funded your first net" โ†’ "You funded your 5th net" โ†’ "You protected a whole family" creates continuous momentum. The ceiling (vaccine campaign, trained health worker) represents genuine community-level impact โ€” a long-term aspiration that keeps players engaged for months.

Full Ladder

TIER 0 โ€” Day-One Quick Wins

Before the first net, players feel real impact immediately. Framed as "steps toward your first net."

~5$0.05Water purification tabletVillage well glows blue, child drinks from it
~10$0.10Vitamin A doseSun rises brighter, children's eyes shine
~15$0.15Deworming treatmentChildren run and play (previously sluggish)
~25$0.25Measles vaccine doseVillage health day โ€” shield badges appear on children

TIER 1 โ€” Net Accumulation Spine

The core game loop. Each net is real. Each funds an AMF bed net distribution.

NetsAds totalCostMilestoneEmotional frame
1 net~200$2First net appears โ€” one home protected"You protected a home"
2 nets~400$4Second home lit up"A second family safe"
3 nets~600$6Three homes โ€” a cluster forms"You're building something"
5 nets~1,000$10"First Family" milestone"An entire family. Because of you."
10 nets~2,000$20"Block Protected" โ€” map cluster glows"A neighborhood, safe tonight."
25 nets~5,000$50"Quarter Village" โ€” AMF map overlayReal AMF distribution map fragment
50 nets~10,000$100Village Elder unlocked"Your village. You built this."
Net cost = $2.00 confirmed (AMF). Ads-to-net assumes $0.01/ad eCPM after network cut. At $0.03/ad (realistic North American rewarded video), divide ads needed by ~3 โ€” Net #1 in 5 days instead of 14.

TIER 2 โ€” Community Scale Ceiling

The long-game. Beyond nets โ€” protecting whole communities.

100 nets$200~200 people protected for 3 years"You protected a community"

500 nets$1,000Statistically ~1 child's life saved (probabilistic, GiveWell)THE moment. Handled carefully โ€” probabilistic framing only.

Retention Cadence

At 5 ads/day (conservative):

DayProgress
Day 1All Tier 0 milestones hit in one session (5 ads โ†’ 25 ads)
Day 14Net #1 funded
Day 28Net #2 funded
Day 70Net #5 โ†’ "First Family" milestone
Day 140Net #10 โ†’ "Block Protected"

At $0.03/ad: divide all timelines by ~3. Net #1 in ~5 days instead of 14.

MVP Simplification

Tier 0 micro-interventions can be framed as contributions toward the next net โ€” no additional partner relationships needed at launch:

"You've contributed enough to fund a child's vitamins today โ€” you're 12% of the way to your first net."

AMF only at MVP. Multi-partner (Helen Keller, Evidence Action) in V2 once the game has traction.

๐Ÿšง Open Decision for Gin: Single AMF partnership (net-only, recommended for MVP) or multi-partner from launch (Helen Keller + Evidence Action + AMF)? Recommendation: AMF only at MVP.
