Campus Rush: Session Survival

Create a complete, playable 2D arcade game called Campus Rush: Session Survival for the iDos Games platform. The theme is a funny university student surviving exam week in Kazakhstan. Use a colorful polished pixel-art style, smooth animations, an attractive main menu, sound effects, and mobile-friendly controls. Gameplay: the player controls a student, collects glowing books and coffee, avoids professors and obstacles, earns points, and tries to achieve the highest score. Add increasing difficulty, collision detection, a game-over screen, restart button, high-score display, and a short tutorial. Add a student-themed collectible system, achievements, and a leaderboard UI. Make all gameplay functional, not just a visual mockup. Save progress using the platform's supported persistence features. Use simple, reliable mechanics and ensure the game works on mobile and desktop. Prepare the game architecture for Solana integration using supported iDos Games modules. Do not simulate successful blockchain transactions. Clearly separate working gameplay from blockchain features that still require configuration.
