Honest take
- ✓The game is genuinely fun and already built — not a whitepaper.
- ✓$HOLD's double meaning (hold the core / hold the bag) is viral-ready.
- ✓Wallet-optional onboarding = a wide funnel. Gamers first.
- ✓Skill-based earning beats grind-farming on sustainability.
- ⚠Loose earning caps → inflation. SINK > EARN is enforced.
- ⚠Content can run dry after 8 worlds → leaderboards + seasons fix it.
- ⚠On-chain-game audiences are skeptical → lead with free gameplay.
