Nice puzzle game - I liked how the various levels used and combined the ball / water / spike mechanics in a whole bunch of ways (e.g. break free to place ball vs. break free to go across water vs break free to smash... or sometimes all 3 at once!)
I think it would have been nice to weave in a little more context (e.g. it comes across suitably wizard-y with the decor obstacles, but I don't know if I'm smashing up the tower of the wizard who trapped me, or if I'm the wizard and this is my own tower [in which case, got the keep the cost down!])
