A chaotic fireworks workshop at dusk, shells and sparks flying as friends scramble with scoops and buckets

Games / 04

Boom or Bloom

One more scoop?

Co-op party / simulation · PC (Windows) · Steam

Run a fireworks workshop with up to three friends. Every scoop makes the shell bigger and worth more, and brings the workshop closer to blowing up. One listens with the stethoscope, one steadies the shell, one holds the bucket. Light the fuses at night: a sky full of fireworks, or a crater.

How it plays

  1. A player on fire after a shell blew up on the workbench
    01

    One more scoop?

    Every scoop makes the shell worth more. But every shell has a limit you can’t see, and one scoop too many blows it up on the spot: the workbench goes flying, everyone nearby gets knocked over, and whoever was closest catches fire.

  2. A player with the stethoscope listening at the clamp while friends wait
    02

    Every clue tells only part of the story.

    The pressure gauge, the stethoscope (only the wearer hears how thick the shell is), the workshop cat bolting when a shell is about to blow, smoking shells that keep rising after you stop pouring, and daredevil shells sealed close to the limit that score the most at night — or burst low and hit a guest.

  3. Slow-motion replay naming who caused the boom
    03

    Better with friends.

    1–4 players online: open a room and invite Steam friends, or play over LAN. Hold a shell steady so scoops are less shaky, throw a bucket over a smoking shell (it gets damp and loses value), or shove a friend mid-pour. Whoever catches fire drops flames until someone empties a bucket on their head. Slow-motion replays name the culprit. Solo works too.

  4. A legendary fireworks burst lighting up the night festival
    04

    Put on a show for the whole town.

    Every shell gets a name and a credit. The bigger it is, the louder the crowd. Beat your best of the run for an EPIC, beat your best ever for a LEGENDARY — and the camera swoops in. Sketch mold: draw a shape inside the shell and it bursts into your drawing at night. Every night picks a Best of the night.

  5. The morning shop stocking ingredients, molds and upgrades
    05

    How far can you go?

    16 guided nights for 8 guests, then endless nights with a grand festival every 5. Miss a target and you lose one of your 3 hearts. 8 ingredients, 5 kinds of shells, 5 molds, 6 recipes, 9 firework effects and 9 workshop upgrades in the morning shop, plus 11 legendary upgrades, Fame and 17 permanent perks, a fireworks gallery, 7 ranks, Steam leaderboards and 30 achievements.
