crushd.JPGCrushd is a tough block-stacking puzzler with quite a sinister atmosphere. A red block is pacing the screen, and will climb up green blocks which fall from above.

Clicking the green blocks causes them to explode and pieces of debris fall down below. Red can only climb up a single block, and turns the opposite direction if faced with an unscaleable wall.

If he gets trapped for too long or is squashed by falling debris, he'll shake the area around him, turning blocks into rubble.

It's pretty difficult to get into, but once you get the knack, it's satisfying stuff - especially when the water begins to rise. Go give it a spin on Jonathan's website.
