[iOS][2012] Match-3 game with blocky robot heads

I remember playing this game on my iPod touch (4th generation).

I've tried to recreate how it looked: http://prntscr.com/h31pfx

Title screen of the game looked like a picture on the left ,but colorful - it displayed a cool robot that levitated slightly. At the top of robot there was a name of the game written using 8bit style of letters.

A main game looked like a screen on the right. It contained robots of various types and colors. There was a unique feature - if multiple robots of the same color/type are connected to each other - these robots "evolve" - their appearance are changed to represent cooler robots.

Also the game featured great electronic music - the start of each level music was simple but as you progressed over this level (to unlock 100% of music track) you could hear that music was changing to more energetic one and if you unlock 100% of soundtrack you could listen it independently in in-game music player. Also you could double-tap on any undesired block and it will fly away, but to do it you need to have special little flying machines which you earn by blowing chains of blocks - the bigger the chain of the same color blocks - the more points/rewards you will get.

This game was published in 2 versions - lite version and regular version. I think regular version was free to download, but contained only a few unlocked levels to play and you could buy additional levels/soundtracks via in-app purchases. I believe this game was released only on iPod touch/iPhone - there was not iPad version.
