I want to publish a complete top-down action game that earns revenue through in-app ads. The core of the job is to design and code a fun, responsive experience where the player views the battlefield from above, battles enemies, and progresses through increasingly challenging levels. Please handle everything from basic prototype to final store-ready build: artwork that matches the theme we agree on, smooth movement and combat mechanics, level progression, audio, pause/upgrade screens, and reliable ad integration (AdMob or a comparable SDK). The final package should include the source code, art and audio assets, and clear instructions so I can submit future updates on my own. If you have ready-made frameworks or standout ideas for replay value, feel free to propose them—I’m open to creative twists as long as the perspective stays top-down and the action feels fast and polished.
