A physics game written in xTalk

Pull back and fling the round Bloops at the Grumps' wobbly forts of wood, glass, stone, metal and TNT. Fifteen forts in three lands, a boss at the end of each, and three stars to earn on every one.

How it plays The same rules on a phone, a tablet and a computer

Pull and let go

Pull the Bloop back in the launcher, aim along the dots and let go. Pop every Grump to bring the fort down.

Tap in flight

Zip, the blue Bloop, dashes. Trio splits in three, Thud drops straight down and Boom goes bang. The yellow one just flies.

Wood, glass, stone, metal

Every block cracks a little each time it is hit hard: glass first, metal hardly at all. And TNT goes bang.

Three lands, three bosses

The Meadow, the Dunes and Shroom Hollow, five forts each. The last of each land is a boss's, and the boss is tough.

Stars to earn

Clear a fort with Bloops to spare for up to three stars. Your stars and best scores are kept for your next visit.

Made with OXT-Beyond One stack, no web code

Written in xTalk

The whole game is one stack in xTalk Script: its screens, its forts and its rules, with its levels as lines of text. It is one of the Stack Player's samples, so it plays there too.

Real physics

Every block, Grump and Bloop is a body in Box2D, through the xTalk Suite's Box2Dxt extension, stepped sixty times a second by the stack's script.

Made for phones

The Mobile Web library gives it the whole screen on a phone, keeps it clear of the notch, and draws the world again to fit when the phone turns.
