Keepfall

Lay siege with a counterweight trebuchet. Every block, beam and defender is simulated with real rigid-body physics, so towers lean, buckle and topple the way you would expect. Knock out every defender to take the fortress, using as few shots as you can.

How to play

• Aim: press and drag back anywhere on the field, then let go to fire. Drag further for more power. Or use the arrow keys and Space.
• Special shots: tap (or press Space) in flight to split a scatter shot or burst a blast pot.
• Materials: thatch and timber are light and burn; stone is heavy and tough; iron-banded oak barely cracks. Powder kegs explode.
• Stars: clear a level within par for three stars. Stars unlock new regions.
• Siege Road: an endless string of fortresses. Unused shots carry over to the next one.
• Daily Siege: one new fortress every day, the same for everyone.

Keys: ←→ angle, ↑↓ power (hold Shift for fine steps), Space fire, R restart, M sound, Esc levels.
