i enjoy the game but after you get the hang of it its pretty easy you can beat the whole game with wind and earth towers pretty much. my only complaints are the game is slow the speed up button doesn't seem to change the game much maybe try a 3x :/ and i hate that i have to watch the start up cut scene every time i load the game a few grammatical errors but you can still tell what it means. also though the game does time the waves id like to throw even more in at one time many times i sit with 1 or 2 monsters and have to wait for the next wave button to light up id rather just time it myself and have the auto timer still there of course.
other than that the game is fun the music fits and the graphic for this type of game aren't bad :D.
