I really enjoy the game and the idea is pretty awesome too, but there should probably be more than just 3 levels per upgrade. I mean seriously, i thought that having a map full of towers would be overkill, instead I'M the one doing the killing and the towers just disappear at the beginning of each wave pretty much.
it's a pretty fun game and all, but my god the tournaments are ridiculously long and you don't even atleast get experience for each fight you atleast won when you lose... itd be kinda nice to have a tournament tree so that you can see how many fights you have left so you don't waste your potions healing when you don't have to
I don't know what gave me the urge to listen to the mortal kombat theme while i played this game, but it fits oh so well with time attack, especially when alot of blobs start shooting onto the screen and u run them into a nice bloody mess with a lawnmower..... FATALITY!
