### 3/5 — Frustrating due to glitches

*2022-02-06*

It’s a fine game, ok puzzles. Sometimes the glass is full and you don’t win, and a LOT of the time the hit boxes for the pipe are MUCH larger than the sprite, so it’s frustrating to draw around it. These are gamebreaking and caused me to delete it.

### 1/5 — Great game not enough levels ?

*2020-02-21*

Played all 100 levels got 3 stars on every level and now there’s nothing left to do so I have to delete it
