Yowl Mirror Arc

Clear rows by completing the rule shown at the top of the board. The board grows one row each wave.

Yowl Mirror Arc is a quiet arcade-puzzle hybrid that grows the play board one row per cleared wave. The board caps at eight rows and the run shifts into a survival score chase at the cap. That structure gives the loop two distinct phases and the second phase is where the design earns its rating.

The growing-board mechanic is well-tuned. Each new row adds one rule cell at the right edge that modifies the wave clear condition. By the time you reach eight rows the clear condition is layered enough that the board feels like a mid-tier puzzle game rather than an arcade.

The session length suits short rides. I played across two Osaka Osaka subway commutes and one evening pass. Auto-save resumes mid-wave. Touch on phone is the natural input; desktop also works.

The score-chase phase after row eight is the weak spot. The scoring rule is fine but the visual feedback is thin, so the chase feels like a stat readout rather than a sustained challenge. Three stars; the build-up phase is the strongest section and the chase phase needs more polish.
