Runtime and Editor compilation and startup of all four demo scenes were checked in the tested configuration. No new features or gameplay changes are introduced. The Update 8.0 tutorials, screenshots, Smart Custom Editors and independent prefab workflows remain applicable. Use Unity 6000.6.5f1 as the reviewed editor baseline for this edition. Version 8.0 package checks and earlier release details below are historical context, not additional 8.1 test results. #### Update 8.0 features retained in 8.1 Create a 2D runner using the existing component framework, demos and 14-tab editor workspace. Update 8.0 adds a shared dark-and-yellow editor design, Smart Custom Editor guidance, independent prefab copying, safer terrain cleanup, projectile flight limits, one-time enemy death and recovery-aware level progress.

### What is included * Run and FlappyBirds character modes; character, camera, terrain, backgrounds and combat components. * Coin/life pickups, chests, melee/shooter weapons, projectiles and a coin-based shop. * Level unlocks and best ratings with stable campaign/level identities and recoverable save migration. * Optional Advertisement Legacy integration. Unity IAP package management is present; a built-in real-money purchase/receipt/restore implementation is not included. * English offline Documentation.pdf, current screenshots and online step-by-step tutorials. ### Compatibility and release status This documentation describes the reviewed Unity 6000.6.5f1 Built-in project. It does not promise support for every older editor, clean import or device. Remaining legacy serialization, unresolved references, TMP setup and 2D/3D shared asset GUIDs still require release validation. The engine retains legacy Input Manager; do not switch to New Input System-only to hide a warning. ### Earlier release history — retained for reference The entries below describe past releases, not additional promises for 8.0. Historical claims that “all warnings” were fixed or that Console messages were removed are not a current clean-import guarantee. Update 8.0 resolves causes and reports remaining issues; it does not recommend hiding messages. * 7.6: Unity 6 support; project updated to Unity 6000.0.43f; editor fixes and warning cleanup were reported. * 7.5: project updated to Unity 2022.3.49f1. * 7.0: updated demos and editor fixes; project updated to Unity 2022.3.38f; level creation, runtime saving, unlocking and star ratings; input assignment/touch controls; redesigned UI windows and missing-reference checks; scene-configured banner, rewarded and interstitial Ads with an animated rewards window. * The older input announcement mentioned gamepads. The current supplied character reads configured KeyCodes or SimpleInput touch axes; FlappyBirds uses click/tap. Verify a gamepad mapping explicitly instead of assuming a separate gamepad mode. ### Existing videos [Original presentation](https://www.youtube.com/watch?v=3uGd9zMHkE0) · [Original Ads tutorial](https://youtu.be/bh05rLBIlns).
