A complete, fully documented one-touch arcade game: cannon shop with 16 skins, six-stage difficulty curve, lives, medals and saved progress. Reskin it and ship, or lift out just the systems you needReady to use solution for: Windows, Mac OS X, Android, iOS, Windows Phone and WebGL.Cannon Crunch is a finished game, not a snippet. Tap to fire, hit the target,dodge the rotating block — and everything a released game needs around thatloop is already built and wired: main menu, pause, settings, a working shop,game over, persistence, a progression curve and monetization hooks.If you want to ship a casual game, this is a complete product you can putyour own art and audio into. The whole screen flow works, purchases and highscores already persist, and the difficulty is tuned through an asset ratherthan buried in code. Replace the sprites, retune one profile, publish.If you want to learn or borrow the structure, the codebase is the reason tobuy. Gameplay logic lives in plain C# services with no MonoBehaviour coupling —score, audio, skin catalog, rewards, difficulty — each reachable through oneproperty and each replaceable on its own. Saving sits behind a single interface,so moving progress from PlayerPrefs to a file or a cloud backend is one line.Every public member carries XML documentation and every inspector field has atooltip. Two assembly definitions keep the package out of your global compilescope, so it cannot collide with your own code.Genre fit: It is built for casual and hyper-casual mobile: portrait,one-touch, endless, session-length runs, with the reward and interstitial hooksalready marked. The pieces generalize well beyond that — the shop, thepersistence layer, the score and medal system and the difficulty director allwork in any 2D game, and the difficulty director and Mathfx helpers have no UIdependency at all.How customizable is it? The things you will actually want to change are data,not code:Cannon skins are entries in one asset — sprite, muzzle position and price per skin. Adding one is a list row, and the shop picks up the new count itself.The whole difficulty curve is a second asset: six named stages, each setting rotation speed, reversal timing, speed waver and reversal cadence. Values interpolate between stages, so retuning the pacing never means editing code.Audio, colour palette, lives, fire rate, medal thresholds, reward cooldowns and the bullet's speed and layering are all inspector fields or named constants, documented in the manual with defaults and locations.Want to plug in your own HUD, effects or sounds? Subscribe to the events the services raise — score changed, medal changed, skin equipped, difficulty stage reached — instead of editing the package. Your changes then survive every update.The package ships with an 800-line manual covering the architecture, the roundlifecycle, a full API reference, extension recipes with code, a tuning table, atroubleshooting section and instructions for stripping it down to only the partsyou want.All artwork comes from the Cannon Pack asset package.-- -- --University of Games small research center for indie game developers.
