Problem

Client Background

The game needed better runtime stability and level design balancing to retain action-game players.

Critical Risk Area

Technical instability and progression imbalance were reducing long-term player engagement.

  • Performance drops in combat scenes
  • Low mid-game retention
  • High crash reports on older devices

Solution

Delivery Outcome

We optimized rendering pipelines, level pacing, and reward balancing for action-focused retention gains.

Why this approach

Action games require stable frame delivery and balanced challenge progression to keep players returning.

Process

How we made key decisions, handled technical complexity, and applied engineering expertise to deliver measurable outcomes.

1

Product & Architecture Decisions

  • Segmented effects-heavy assets for memory-safe loading
  • Added automated crash telemetry and issue bucketing
2

Technology Selection Reasoning

  • Unity engine optimization for action scenes
  • C# gameplay systems for deterministic combat loops
3

Complexity Managed

  • Stabilized frame rates during peak combat events
  • Improved retention in mid-level progression
4

System Design Approach

Delivered performance fixes first, followed by progression and reward balancing in retention-focused updates.
