Demon Runner
Demon Runner is a mobile-first endless runner created in Unity, built around fast-paced reflex mechanics and a layer of light RPG progression. Players move through an uninterrupted flow of threats, relying on two key actions: rolling to dodge and striking to eliminate enemies. Every run adds to the score, with distance, timing, and combat all contributing. Game-Ace handled the entire development cycle, from gameplay systems to the launch-ready website, with future updates fully supported by our team.
Core Gameplay Mechanics
Players control a lone knight running through hostile zones filled with traps, gaps, and enemy creatures. Two actions define every encounter: tap to roll under or over hazards, and swipe to strike enemies in close range. Timing determines survival, and the pace increases steadily as the player runs farther.
Every run adds to a visible point counter. Distance, kills, and collectibles influence the final score. Randomized chests appear mid-run, offering temporary boosts or new weapons. A loot box meter tracks progress toward a rare item chest, which spawns when filled. Each opened chest adds to the player’s permanent inventory.
Health is persistent during the session. Mistimed rolls, missed attacks, or collisions reduce the bar, causing it to be depleted and ending the run. This setup turns each playthrough into a race against damage. Some enemies can be skipped with smart timing, while others must be eliminated to survive.
Distinctive Features of Demon Runner
Demon Runner introduces systems that support replay value, short-session intensity, and skill-driven progression:
- Two-action combat system. Every encounter requires players to either roll or strike. Success depends on reading threats and responding within seconds.
- Loot chest progression. Chests spawn during runs and offer temporary boosts or gear. A loot meter builds over time, guaranteeing rare rewards once filled.
- Inventory and upgrades. Items collected from chests can be equipped between sessions. Some increase damage, others offer healing, or reduce incoming damage.
- Score-based competition. All the points are earned by surviving longer, eliminating enemies, and collecting chests. Higher scores unlock new content and reward skilled play.
- Mobile-optimized input. Touch controls are responsive and limited to quick taps and swipes, minimizing complexity while maintaining high engagement.

Technology Stack
Unity was chosen for its flexibility and fast iteration cycles, allowing full-cycle development for both Android and iOS from a single codebase. The engine supports smooth animations, responsive touch input, and lightweight builds optimized for mobile hardware. Backend logic was implemented directly inside Unity, with local systems managing scoring, chest logic, and health tracking.
The in-game UI was built using the Unity UI Toolkit, which allows for quick adjustments during testing and providing clear feedback for all player actions. Animation states for rolling, striking, and damage reactions were kept minimal for performance, yet expressive enough to support the game's fast-paced action.
