Slimestronauts: Burst Strike! is a colour matching puzzle game about dropping brave little Slimes onto a board overrun by Replinodules, and bursting them before they take over.

It's a love letter to the falling-block puzzlers of the classic era: easy to learn, tight to play, with a little more chaos every level. Bosses, obstacles, power-ups and a Mission Control crew that won't stop talking all keep things moving.

DROP

Steer each capsule of Slimes as it falls. Rotate it, slide it, and when you're sure, Slam it straight down.

MATCH

Line up matching colours with the Replinodules on the board. Bigger lines and streaks score more.

BURST

Burst every Replinodule to clear the mission. Set up chain reactions and watch the board erupt.

Small, squishy and far braver than they should be. The Slimestronauts come in three colours - green, orange and pink - and each one only bursts Replinodules of its own colour.

They don't do it alone. Mission Control watches every drop, its Operators chiming in with warnings, advice and the occasional cheer when things go well.

GREEN ORANGE PINK

Replinodules are pulsing, colourful growths that cling to the board - and they don't sit still. Leave them alone and they spread, connecting to their neighbours and filling in the gaps you were saving for later.

When Mission Control calls out "A connection is made!", it's already too late for that corner. Burst them fast, or plan around them.

Some missions end with a boss that changes the rules of the board. Others throw obstacles into the mix, like the Clump, a sticky lump of goo that has to be smashed out of the way.

Power-ups turn the tide: shake the board, beam down help from above, or set off something much bigger. Just watch out for the corrupted ones.
