It's okay game for what it is. It's been made pretty well in terms of quality. Working well, no bugs, good visuals, okay animations. Adventure mode is sometimes challenging a bit, but whole point is unlock all modificators in adventure mode and than play with your friends in pvp on local\steam remote play together. So there is main problem - WHERE IS MOST CHALLENGING AND INTERESTING MODIFICATORS??????????????? You can unlock them and they work only in adventure mode. Smart in reverse.
Actually you can buy it (there is not that much games like this and it's not that bad, if you know why you need it), but do it on sale :)
