Many fishing arcade games are built around coin sinks, online rooms, or casino-like economies. Reef Cannon provides a compact offline alternative: skillful target

App Description: This app is a single-player arcade-style fishing game. Players fire various projectiles into vibrant coral reef channels to catch stylized fish, build combos, and use earned shells to upgrade between rounds. The product must deliver the quality of a polished mobile game: a bright cartoon art style, tactile controls, a clear progression path, replayable objectives, a persistent upgrade system, pause/results screens, and an offline-ready experience from the very first launch.

#Core Features

1. Playable fishing scenes featuring swimming fish, aiming, shooting, hit detection, capture probability, reward mechanisms, and penalties for missing.
2. Four projectile types, each with unique costs, cooldowns, visual effects, and advantages against specific targets.
3. At least ten fish species/targets, varying in value, capture difficulty, movement, and behavior patterns.
4. Level/round structure, including objective setting, timers, ammo limits, and performance ratings.
5. "Tide Streak" meter, featuring reward multipliers and a buffer mechanism to prevent combo breaks.
6. Upgrade Dock for enhancing projectile power, reducing cooldowns, increasing ammo capacity, and improving special shot efficiency.
7. Collection Log displaying caught fish, rarity, highest combo counts, and brief background stories.
8. Daily Reef Challenge, generated locally based on the date (seed-based) and requiring no internet connection.
