coin, star — pickup sprites with sparkle frames
grass — 16×16 platform tileset, 12 tiles
dungeon — dark bricks and ladders
sky — parallax clouds, day and night

burp — yes, the burp button ships with this
Every asset in the starter pack is CC0: public domain. Use them in prototypes, jams, shipped games, school projects and ads. No attribution required, though a mention makes the bomb mascot blush.
Load them with the built-in loadSprite() / loadSound() helpers and start composing blocks.
