HTML5 Platformer

A short, sweet, side-scrolling platform level built on pure HTML5 Canvas.

About the Platformer

The side-scrolling platformer is one of the most beloved genres in video game history. Beginning with titles like Donkey Kong (1981) and Super Mario Bros. (1985), the formula of running, jumping, dodging hazards, and collecting items defined an entire era of gaming. Our HTML5 Platformer is a loving tribute to that genre — a short 2D side-scroller built entirely with vanilla JavaScript and the HTML5 Canvas API, with no game engine and no third-party libraries. It showcases what modern web browsers can do out of the box.

The game features hand-animated sprite cycles for run, idle, and jump states, parallax-scrolling backgrounds for a real sense of depth, collectable coins and power-ups, a title screen, a pause menu, and enemy characters to dodge or dispatch. The level is intentionally compact: one focused stage that an experienced player can finish in a couple of minutes but that still rewards exploration. Because the entire game is client-side JavaScript, it loads in less than a second on a modern connection and runs smoothly even on low-end laptops.

How to Play the Platformer

On desktop, use the left and right arrow keys (or A and D) to run, and press the up arrow, W, or the space bar to jump. Hold jump to reach higher platforms. Collect every coin you can reach and try to finish the stage without falling into pits or bumping into enemies. Some builds let you attack enemies by pressing K. On our mobile build we provide an on-screen D-pad and action buttons just below the canvas so you can play comfortably with one or two thumbs.

Strategy Guide: 7 Platformer Tips

  1. Learn the jump arc. Every jump has a fixed shape. Spend the first minute just jumping on flat ground to feel exactly how far you travel.
  2. Look before you leap. When approaching a gap, pause briefly to see the full length before committing.
  3. Use variable jumps. Tapping the jump button gives you a short hop; holding it gives full height. Use the short hop for small gaps to avoid overshooting.
  4. Rhythm beats reflex. Moving enemies follow fixed patterns. Sync your running speed to their cycle rather than reacting to every step.
  5. Momentum is your friend. Do not stop-and-go. Build speed on flat sections so you can clear the longer jumps.
  6. Explore up and back. Some collectibles are above the main path or behind the starting point. Hidden rooms reward curiosity.
  7. Practice safe landings. When landing near the edge of a platform, release the direction key to stop. Holding the direction key after landing often walks you straight off the far edge.

Common Mistakes

  • Holding jump on every leap. Full-height jumps send you past short platforms — use short hops for short gaps.
  • Running blind. Do not sprint off-screen without a quick pause to look at the layout.
  • Ignoring enemy patrol patterns. Once you notice the cycle, the level becomes much easier.

FAQ

How many levels are there?

The upstream release ships with a single, carefully designed level that teaches every mechanic and rewards exploration. It is a "perfect bite" rather than a full game.

Does the game work on my phone?

Yes. We added an on-screen D-pad and action buttons under the canvas. Controls map one-to-one to the desktop keyboard, so you can play with one thumb or two.

Is there a save system?

No — the level is short enough that a save is not required. Plan on finishing in one sitting.

Does the player lose progress on death?

Falling into a pit resets you to the last checkpoint. Running out of lives restarts the stage.

Can I attack enemies?

Yes, in most builds pressing K or the "Attack" button executes a short melee swing. You can also jump on some enemies to defeat them.

What FPS does the game run at?

A locked 60 frames per second using requestAnimationFrame. On lower-end devices it gracefully degrades to 30 fps without breaking the physics.

Can I use a gamepad?

Many modern browsers support the Gamepad API. If you connect a USB or Bluetooth controller, the D-pad and action buttons should be recognised. If not, you can map a controller using third-party tools such as JoyToKey.

Is the source code available?

Yes, the platformer is a forked open-source project. You can inspect the JavaScript by viewing the page source or exploring our public repository.
