### 5/5 — so hard

*2015-02-05, version 1.2*

### 3/5 — Awesome!

*2015-02-05, version 1.2*

Cool puzzle game and easy to learn, it has nice themes added to it for playing.

### 4/5 — Nice Twist On Match-3 Gameplay

*2015-02-03, version 1.2*

This game differs from other match-3 games with the adding up to 10 aspect of the gameplay, which, along with the timer keeping you on your toes, creates a game that isn't like the others in the genre. It's not that entertaining in the long run though

Update 1.2: The new addition of the brutal mode is quite nice, and it did end up garnering some more playtime from me. I'm not sure a lot of people may like that though

### 4/5 — 👍

This is a new kind of puzzle/against the clock game that gets me hyped and keeps me interested. Brings a lot of joy to my life :)
