Evolution
| Stage | Requirement |
|---|---|
| egg → blob | First interaction |
| blob → cat | age ≥10, feedings ≥15, plays ≥10 |
| cat → dragon | age ≥30, feedings ≥50, plays ≥40 |
Check evolution after each interaction. Announce with fanfare.
Death
Pet dies if: hunger ≥ 100 OR happiness ≤ 0
BUT if immortalMode: true in config, pets don't die — they just get very sad and hungry. Stats cap at 99/1 instead of triggering death. Default is immortal mode ON.
Show memorial (if death enabled), offer new pet to restart.
Decay (Cron)
Set up cron job openpet-tick every 2 hours:
- hunger +15, happiness -10, energy -5
- Clamp all stats 0-100
- Check death conditions
- Alert owner if critical (hunger >80 or happiness <20)
- Increment age daily
