AWESOME game, finished it :D :D some levels were a bit of a challenge, really liked the last level!!! Some parts its better to stick to wall, bomb and spikes. Sometimes its really tempting to use that chaing ball :D If i remember level 16, make the turret infront of the princess or behind without breaking(i hated that part), just follow with the wall and bombs and then continue like that until u can make another turret. Hope it helps
