Leonar Crown

Leonar Crown is a self-contained, offline arena battler built entirely in Flutter for Android. The app combines a full top-down action game with multiple interactive sections, all wrapped in a strict monochrome visual language of black, white, and gray.

The core of the experience is a real-time arena where the player controls a champion from a top-down perspective using a virtual joystick and a dedicated fire button. Enemies spawn in escalating waves, each level raising the pressure with faster and tougher opponents. Pickups for health restoration, shields, damage boosts, and rapid-fire cadence appear on the field, creating split-second risk-reward decisions between pushing forward and retreating behind cover.

Three distinct arena modes offer variety. Crown Siege is a level-based survival challenge with no time limit, testing how far the player can climb through increasingly difficult waves. Ninety Surge is a timed sprint that compresses the action into ninety seconds of non-stop scoring. Sovereign Clash is a focused duel against a single fortified rival supported by escort units, demanding precise spacing and timing.

The Champions section lets the player choose between three fighters, each with unique stats for speed, durability, firing cadence, and impact. Silver Mane favors mobility, Iron Sovereign trades agility for punishing volleys, and Crown Guard sits in the balanced middle ground.

An Insights section presents curated articles on game design topics such as flow states, visual contrast, muscle memory, pattern recognition, and session pacing. A separate tips panel offers practical advice for each arena mode. The Records screen tracks personal bests, total takedowns, match count, time in the arena, and unlockable achievements tied to gameplay milestones.

Settings give control over sound effects, ambient music, haptic feedback, difficulty scaling across three tiers, and a choice between joystick and drag input.

Every screen outside of gameplay features a continuously scrolling wide banner background that moves seamlessly from right to left, layered beneath a subtle animated grid, reinforcing the monochrome atmosphere without distracting from content.

All image assets are stored in WebP format to minimize application size. The app requires no internet connection, collects no personal data, and stores progress exclusively on the device using local preferences.

Leonar Crown stands apart by delivering a complete, polished arcade experience with multiple interactive sections, a cohesive dark aesthetic, and zero reliance on network services or data collection, all inside a single lightweight Android application.
