Veyr very good
Amazingly good game, I actually finished every level and got every unlockable item, which I never do because in other games as I usually get bored, but not with this one. I really loved this and it was very entertaining to me.
The one level I didn't like was Level 21: it takes ages for the balloon blocks to lift up your green blocks! Actually I didn't really like the balloon blocks all together, but it's no big deal.
Blosics 1 was great too, but this is really 100 times better.
It would be cool to also have a 3rd Blosics sometime :)
