### 1/5 — Doesn’t indicate

*2024-01-01*

Doesn’t say you’ve completed the puzzle. Just keeps on counting time

### 1/5 — Too slow, clunky and glitchy

*2016-09-10*

It'd be cool if the whole row moved when you click it or any square in that row. Also it should stop the timer if you complete the puzzle before time runs out. Also swiping would be nice too and a more fluid design
