nice !
the visual style was great.. the first puzzle was an original idea.. the second was a good twist on a classsic. the third I personally found annoying and way too long.. could've been bareble with 3 tries.. 5 is too many. sound effects were smooth and well used. background sound when added would greatly increase the vibe of the game.
all in all - new concept, great potential, great execusion, make more (of the original stuff not the Simon stuff.. please :) ).
