Nice and relaxing to play, although my game also froze with constant 'absorbing' sounds like Karnil described it after using too much powerups and absorbing too much, i guess.
@sirwoofy: good tip, but does not always work. say if a wave thingy is finished, then your game will not continue (some ninjas will stand there and you'll be stunned) :D
Why can't I overread all the cmts about 'first easy, then hard', just rush hard and use a stupid amount of time to get the medium badge last? Oh, I can.
hm.. nice, but sometimes not so innovative/well made as other games. 1. in lvl 'think with brain and eyes' you can be mashed although you already opened the door and walked away. 2. i expected the unexpected, so.. =)
@Tryko: There were no Winged Boots. Brian told me where they should be, but they weren't there. So maybe bugpreventing by the creator. (+) so everyone knows.
