### 4/5 — Good concept

*2015-09-25*

I like the concept, haven't come across anything like this so far. But I think the presentation can be improved. The typing-like text animation gets tedious after a while, especially with sound on. Also, after I complete each level, I need to tap once to take me to the main menu and then choose the next level. I should be able to just move on to the next level with just one tap, and have a separate button for main menu. Also, there's a nasty (but rare) bug when you enter some levels, the typing-like text animation sound plays infinitely which is extremely grating!

### 5/5 — Definitely like an updated Rubix cube

*2015-09-24*

Nice game, the trick is, when ever an "o" is on a square and it's on, then any "o" will turn the square on. Otherwise any "n" will turn it on. Once you've got that it's just shifting until you get pieces in the right places. Cool idea.

### 5/5 — Assez sympa

*2015-07-20, version 1.1.2*

Trouver la bonne combinaison pour allumer tous les blocs, c'est assez sympa et les nombreux niveaux permettent de jouer longtemps !

### 5/5 — Bon jeu de réflexion

### 5/5 — Original

*2015-06-17, version 1.1.2*

Super fun and well designed!

### 4/5 — Addictive cube game

*2015-06-17, version 1.1.2*

This is quite a tricky game, but nicely done. Bad play is punished by running out of tokens which means you need to buy our earn more.

### 5/5 — Прикольная головоломка

*2015-05-28, version 1.1.1*

Необычная логика. Интересный дизайн. Огромное количество уровней. Игра явно не на один вечер.
