It's good that it's easy!
It's a very nice puzzle game, I really like those beautiful chains it builds up. And while others complaining about it I actually like that I don't have to think hours about the solution of a single level, instead it can be found out in a few minutes if someone gets the hang of it. I'm not a fan of those puzzle games that are getting too hard.
I didn't really like the music but it can be turned off, so that's not a big problem. The sounds are good.
The only thing I didn't like is that you have to select each element you wish to place. It would be much better if I only had to select the element type and then I could place every element of that type.
And while the chains are very visual, that's only becouse their length; they could look even better with some explosin animation and sound or something similar.
