Good game. The game Area could be larger. Also after discovering combinations it'd be less annoying when one could just choose what kind of tower to make. With a small area, hard to click the right spot.. its actually frustrating to build the right tower.. somtimes u just make a mistake and do the wrong combination.
This is one of the best flash games i've played even though I'm usually no fan of platformers. It qualifies for even more badges as it last so long and has the "mini" and modes as well.
