Annoyingly addictive
I keep finding myself coming back to this game, so it's got to be at least a little bit good.
The only issues I have with it are that some levels (especially challenges) have to be absolutely 100% accurate, there's no room for mistakes or you'll have to start all over again. While that makes it challenging, it can take from the fun a lot.
Also, the walkthrough is only any use if you've already completed the game and are looking for help on the challenges.
Anyway, looking forward to the possibility of a Blosics 3!
