Tube Agate

Tube Agate is a relaxing pipe-connection puzzle. Tap any pipe piece to rotate
it 90 degrees and build an unbroken channel so the water can flow from the
blue inlet on the left all the way to the outlet on the right.

How to play:
- Tap a pipe to rotate it.
- Connected pipes glow blue when water can reach them.
- Every tap costs one move, so plan your rotations carefully.
- Finish with more moves left to earn up to 3 stars per level.

Features:
- 12 handcrafted-difficulty levels growing from a cozy 5x5 grid to a tricky
8x8 challenge.
- Straight pipes, elbows, T-junctions and cross pieces, plus decoy dead-end
pipes that try to mislead you.
- Satisfying water-flow animation the moment your pipeline connects, with a
bubbling burst at the outlet.
- Level select grid with locks and star ratings, progress saved automatically.
- Gentle synthesized soundtrack and sound effects, with separate toggles.
- Clean, fully procedural visuals. No ads, no accounts, no tracking.

Whether you have a minute or an hour, Tube Agate is a calm little brain
teaser about the joy of making water go where it should.
