This game looks interesting and the artwork is something new and different.
Although it would be nice to have a tutorial portion in the beginning for those that do not understand how to play the game.
Music is nice and flows well with the game.
I gotta be honest, this was surprisingly addictive. I found myself spending far more time on this game than I should: the graphics were bright and inviting, the music was a nice little mix (though I could have done with a liiiiittle more variety - three or four times through the mix, I had gotten the point), and the gameplay was deceptively simple. In many ways, it reminded me of your basic match-match game, but the added rules and gradually increasing difficulty took it a step above.
The only real suggestion I can give is that I could have done with an in-game tutorial - it's a bit daunting when the instructions seem to be just a massive wall of text, and while I picked up the gameplay fairly quickly, it took me a round to figure out that there was a limit on when you could pick up the heart bonus (I haven't played the first game yet).
Otherwise, great game!
Hey tgryphon! Thanks for you great review of Connect Creatures 2. I will think about you suggestion to make an in-game tutorial and maybee ad more music-numbers in the next connect-game.
