Sprout Blaster

Sprout Blaster is a complete, cheerful HTML5 campaign platformer for desktop and mobile browsers. Guide a little sprout hero through 10 hand-crafted stages, defeat every monster by stomping them or blasting them with the pea-shooter, then reach the exit door to unlock the next stage. All artwork is generated from SVG code and every sound effect plus the background music is synthesized at runtime with the Web Audio API - the download contains zero binary asset files, so every sprite and sound is editable in plain text.
