About Cloud Tower
Cloud Tower is a one-button stacking game. A block slides back and forth above your tower, and a single tap drops it. Where it lands on the block below, it stays. Where it hangs over the edge, it is trimmed away. Stack carefully and the tower rises through the clouds. Stack carelessly and the blocks get narrower.
There is nothing to learn beyond that one tap, and no physics to wobble. The challenge is a steady rhythm and a steady eye.
How it works
Your tower starts on a wide base, with a block 110 pixels wide swinging above it. Each drop keeps only the part that overlaps the block beneath. A perfect drop keeps the full width. A drop that is 20 pixels off keeps 20 pixels less, and the block never grows back.
- A drop that barely touches the tower counts as a miss. The first miss is forgiven, and the block keeps swinging. A second miss in a row ends the tower.
- A good drop clears your miss count, so one slip never counts against you later.
- The tower also ends if the block gets narrower than a small sliver.
- The block speeds up as you climb, reaching top speed at about twenty blocks.
- When you finish, the sky region you reached is named: Cumulus Base, then Nimbus Stratum at six blocks, Cirrus Peak at twelve and Celestia Horizon at twenty.
Tips
- Tap when the block crosses the middle of the tower, not when it reaches the edge.
- Be bold at the start. The base is wider than your first block, so you can be up to about fifty pixels off and still keep the full width.
- Count out a beat. The block moves at a steady pace, so a regular rhythm works better than reacting.
- Do not rush after a good drop. A narrow block needs a more exact tap, so slow down.
Why it feels satisfying
Cloud Tower gets its satisfaction from rhythm. The block moves at an even speed, each landing makes a soft triangle-wave note, and the notes climb a little with every block until they reach the top of the scale. You hear your progress. The ending is a quiet card with your height, with no scolding.
Questions
Why is my block getting narrower?
Each drop keeps only the part that overlaps the block below. The more you are off, the more you lose. The width never comes back, so accuracy early on keeps the tower wide.
What ends a tower?
Two bad misses in a row, or a block narrowed to a sliver. A good drop in between resets the count.
