Genre: Idle Simulation / Business Tycoon
About:
A delivery service business tycoon idle game with infinite upgrades and multiple city maps to expand into. One of several idle games built during this period.
Goal:
Build a slow-paced idle game around a delivery business theme, targeting strong retention and session engagement. Isometric 3D art style with full delivery empire management — fleet upgrades, route optimization, city expansion, and idle progression.
Results:
| Matrix | Results | Targets |
|---|---|---|
| CPI (Android) | $1.50 | < $1.00 |
| D1 Retention | 20% | 30–40% |
| D7 Retention | 8–10% | 25% |
| D7 APPU | 800s | 1200s |
Challenges:
Technical
· Designed an infinite upgrade loop using idle game math — cost vs. reward graphs simulated to hit 1200s session time and 30–40% D1 retention targets.
· Integrated crowd combat, giant monsters, and tower systems in a cohesive village environment.
Creative
· Built a runtime city generator using image pixel colors to place and orient road/building assets dynamically via Scriptable Objects.Skills: Idle game math · Runtime level generation · Scriptable Objects · Game balancing
Key Learnings:
Well-structured, handover-ready codebases with a common system design across studio projects save significant time and reduce onboarding friction.
