Context
Second Nexenova release on Google Play. A one-touch 2D car game that ships an endless mode and a finite level mode from the same project.
The problem
Endless and level modes want different win conditions, different difficulty curves and different failure states — but duplicating the game loop for each is how a small codebase rots. The modes had to diverge in rules while sharing everything underneath.
What I built
- Built both modes off one gameplay core: an endless run with escalating difficulty, and a finite level mode with explicit win/lose states.
- Put ads, real-money purchases and remote tuning behind a single shared platform layer, so no gameplay code talks to a vendor SDK directly.
- Integrated ironSource LevelPlay for mediated ads and Unity IAP for purchases.
- Used UGS Remote Config to retune difficulty and economy values after release without a store update.
- Server-owned progression and currency through UGS Authentication, Cloud Save and Economy.
