SkySprout: a platformer that ships not a single image
SkySprout is a tiny pixel platformer drawn entirely by code. A 480×270 canvas, and the game holds not one image file and not one sound file: sprites, palettes and music are generated on the fly. The whole story fits in a line — a little sprout sets out to return light to the sky and gathers nine sun shards.
Three worlds, three palettes
Each world is 180–196 tiles with its own color scheme, defined by data rather than assets. A sunlit meadow by day, a glowing grotto at night in cold purples, and treetops above the clouds at sunset. Sprites are painted into a helper canvas and scaled up, so the pixel art stays crisp on both a monitor and a phone.
What gets in the way, what helps
Three sun shards hide in every world, with a mid-level checkpoint and strict time checkpoints. There are two kinds of enemy — beetles and hoppers — and both are dealt with by stomping them mid-jump. A sun fruit grants a shield: it absorbs one hit and lets you break brick blocks from below. Every 50 coins adds a life. Your personal best and the sound settings are saved right in the browser.
You have to hold the jump
The controls are honest and ask for a good hand: arrows or A/D move the sprout, and Space, W or up jump — the longer you hold, the higher you go. Wide gaps cannot be cleared without the Shift run. P or Escape pauses, R restarts, M mutes. On a phone, on-screen arrows and a jump button appear at the bottom.
Well-mannered tech
The game synthesizes sound through Web Audio, honors the system prefers-reduced-motion setting, and pauses itself when the tab goes to the background. Nothing flickers or hums in a neighboring window.
Demo mode
The "Demo" button runs an autopilot: it runs right with a sprint and jumps when it hits a wall or a gap. The score and the loss condition are computed by the same game a human plays — the autopilot does not fudge the result.
The bottom line
SkySprout proves a real platformer needs only a canvas and some code. Three worlds, nine shards, shields and hoppers — and nothing to download. A little game, a big adventure, exactly as the tagline promises.
