### 5/5 — Great simple game

*2019-02-18, version 1.5*

Dead simple and my kids and I love it. (Not a game where I have to worry about leaving them alone with).

It’s retro in it’s simplicity and breakneck speed and sound FX. 

The insane level really is insane. 

The music is not aggressive other than upping the tension while the maze slowly speeds up as you progress. The video game equivalent of being a frog in a pot of slowly boiling water 😉

### 5/5 — Great!!

### 3/5 — Addictif

*2014-11-19*

Un jeu simple mais amusant, dommage tout fois que la qualité de l'image (en tout cas pour iPhone 6 Plus) ne soit pas la, d'autant plus qu'il n'y a pas grand chose à faire.

### 5/5 — Jr4
