Scaleflint

A gecko has fallen down a flint chimney and the water is coming up after it. Slide, kick and hop from wall to wall until you burst out into the morning sky, eight shafts in a row.

The gecko grips: holding towards a wall and jumping gives a short hop straight up it, three per wall, refilled when you touch the other wall or the ground. Chain wall jumps and hops to climb faster than the water rises.

• 8 shafts: from a mossy flue of 50 rows to the 148-row Flint Crown, each checked climbable from the start and from every checkpoint
• Rising water: it never stops, and it speeds up when you are far ahead, so there is no camping
• Hazards: bone spikes on walls and ledges, crumbling sandstone ledges, wind vents that push you across the shaft
• Checkpoints and lives: flags on wide ledges, three lives, an extra life for every 30 flies
• Guided first climb: the first shaft teaches jump, wall jump and climbing hop one card at a time, and a red pulse warns when the water is close
• One-thumb touch: tap the side you want to jump towards; keyboard play with arrows and Space
• Score: stage bonuses, flies and lives left; your best score and highest stage are saved
