  • Water Presets: Uses Canvas vertical linear gradients shifting colors depending on selected presets.
  • Asset Preloader: Detects base64 strings and preloads HTMLImageElement resources asynchronously on query change.
  • Local Compression: Serializes settings into a JSON string and encodes to URI Base64.

Physics Formulas

  • Steer Velocity: `player.speed = 4 * speedMultiplier`. Adjusts target glide speed.
  • Eating Incremental Mass: `points = defaultPoints * growthMultiplier`. Scales visual growth rate.

Answers

Frequently Asked Questions

Q How does the custom photo avatar feature work?

You can upload a portrait photo of yourself, a friend, or a cartoon mascot. Our in-browser image processor crops and attaches the face to the swimming fish body with animated tail physics.

Q How does the Creator mode differ from standard Grow-a-Fish Play mode?

Standard Play mode features fixed progression and default fish skins. The Creator mode lets you modify evolution thresholds, predator spawn tables, water physics, and custom visual avatars.

Q Can I adjust the game difficulty for younger children?

Yes! You can lower predator speeds, increase friendly plankton spawn rates, or enable Zen Mode so the player fish can swim peacefully without taking hazard damage.
