Hamsuri : Bomb Festival

From the Devs

Trap your friends with explosive droppings, send their bombs back and burrow out before the payback. Hamsuri: Bomb Festival is an arena party brawler for 1–4 players, locally or online, with CPU opponents for solo play or filling empty seats. One arena, four rivals: who will demand a rematch?

A well-placed bomb opens a path. A chain reaction can close every escape route. Smash crates, grab power-ups and keep an exit in mind: your next trap might catch you instead.

Stash a bomb in your cheeks, carry it across the arena and spit it out to surprise a rival. Burrow out of trouble, kick danger down a lane and make the most of the power-ups you collect. Four characters. Plenty of ways to ruin someone else’s plan.

From Sakura’s cherry blossoms to Taiko’s drums, each stage calls for new tricks. Shifting tides, slippery ice, lightning and disguises: learn to use the surprises across 13 arenas, including one secret arena to unlock.

Osaka Dotonbori turns food counters into moving bomb lanes. Read the conveyors, then use CHEF TONGS with a direction + SPECIAL to move the adjacent bomb one tile to your right without stopping its fuse. Time your move and keep an escape route.

At Mount Fuji, lava channels and eruption warnings change the safe paths. Collect the COOLING FAN and use a direction + SPECIAL to cool up to three forward tiles for six seconds. Everyone can use that temporary crossing — including your rivals. Watch for the lava to return.

Hold CHEEK OUT to charge your spit, then release. Interior blocks make your bomb hop onward; hitting another bomb adds fire range while keeping the receiving bomb’s countdown. The last spitter earns its explosion points. A reinforced bomb grows 25% once and cannot go back into cheeks. Shots into rivals knock them down briefly; shots outside the arena or into closed zones are refused.

One round for laughs. A championship for the crown.

• Score Attack: rack up points, respawn and chase a comeback.

• Battle Royale: read the warnings before danger strikes.

• Last Hamster: be the last hamster standing.

• Festival Championship: battle across arenas for the overall crown, with comeback advantages to keep the rivalry alive.

Choose your rules, mix friends with CPU opponents, adjust their difficulty and customize your keyboard or controller bindings.

A game from my younger days. A new generation.

“Back in the mid-2000s, I was coding the first version of this game for the GP32 handheld. Now that I’m a dad, I wanted to bring it back so I could play it with my daughter — and share those matches with you.”

This new version moves from SDL to Unity. AI tools helped modernize the code and create visual and audio assets. The game does not use generative AI during play.
