Some people wondered: for trophy nr 12 you need to kill 4000 bunnies. It can take quite some time. I suggest you play level 56 a couple of times, loads of bunnies. Not that great a game. 2.5/5 so 2/5 :p
Great game, cleared all levels before badges were added but the hard badge made me try a little harder. The walkthroughs are indeed just one way (and usually not the best way of beating the level.
Maybe an idea: limit the number of times you can freeze time to add some difficulty.
@ people who complain a huge wave wipes them out when the enemy's castle hp runs low: Don't go all out and keep some mana in reserve to fend it off. It's called 'to anticipate' and 'common sense'.
@RedJackDaw: damage= damage taken during level, I think 0 damage means golden medal?
@DharkX: Rocket launcher seems most powerful and convenient for all situations. Can't get past level 12 with loads of two-shot turrets
