Ninja Up: pull back, aim, climb.
Ninja Up is an HTML5 slingshot climbing game template with full source code. A cute cube ninja with an orange headband and a fox mask climbs Japanese dojos, shrines and castles ring by ring: hold, pull back and release, and the grappling rope catches the next ring. The edition has 55 stages in five worlds, an endless mode, 14 interface languages and a ready-to-host game folder, plus the editable TypeScript source.
Slingshot aiming with a second chance
A dotted line shows where the ninja will fly while you aim, and the grappling rope hooks the next ring on arrival. One extra launch is available in mid-air on every flight, so a missed angle rarely ends a climb. Banner checkpoints along each stage save the way up.
55 stages across five worlds
The campaign climbs through Ninja Dojo, Waterfall Shrine, Dragon Pagoda, Storm Rooftops and Moonlit Castle, all the way to the Golden Scroll. Each world has 11 stages, and the 11th is a challenge stage. There are no enemies: the scenery is the challenge, with spikes, fire from dragon statues, crushing gates, shuriken on rails, a rising river, wind, and rings that crack, get wet, spin or blink.
Stars, golden coins and outfits
Each stage awards up to three stars: one for the time, one for collecting 70% of the coins and one for not falling. A golden coin hides in every stage, and collecting them unlocks outfits for the ninja.
Endless Climb and Daily Climb
A separate mode climbs as high as possible, with a saved personal best. The Daily Climb uses the same generated climb for everyone on a given day, with its own best height. Every world has its own music.
14 interface languages and player settings
The interface ships in English, Portuguese, Spanish, French, German, Italian, Dutch, Polish, Turkish, Russian, Indonesian, Japanese, Korean and Chinese. Players can change the language, vibration, less motion, light effects and assisted aim, and set music, sound effects and voice volumes separately.
Optional WebGL light effects
The game draws with Canvas 2D. On top of it, optional WebGL light effects can be turned on or off in the settings, and they switch off by themselves on slow devices or where WebGL is not available.
Your game, your hosting
Upload the contents of the game folder to static HTTP(S) hosting and open index.html. No database, PHP, account or server is needed, and normal play makes no requests to ranking, advertising or payment services. Artwork, audio and fonts are all local. The package also includes an illustrated offline guide in 14 languages and third-party licence notices.
What this edition does not include
Native apps, hosting and custom development are not included, nor are an account system, a server, an online ranking, real-money purchases or an advertising SDK.
Who this template is for
Site and portal owners who want a casual mobile game that keeps players coming back, freelancers and studios who need a base for a client's branded game, and developers who want to learn from a typed TypeScript project.
Customise it
Stages are plain TypeScript data in src/data/, every physics and feel number lives in src/config/tuning.ts, and each language has its own file in src/i18n/. The automated tests include a recorded route that proves all 55 stages can be completed. Run npm test and npm run build, then upload the new build.
