Finished it!!
At last!! i finished lvl. 30!!!
This game's amazing! Those chain reactions are wonderfully designed and on top of that those 'Add - On' Bombs made the game so tricky. And I hated those whale bombs. If they weren't there i would have taken half the time!
The music - That's one thing that keeps you from getting bored no matter for how long you've been stuck on any level.
Good going guys. Make a sequel!
P.S. : You can use moving bombs or obstructions in the next game.
