missing a hold on normal is basically an auto fail... the keyboard reads it as aaaaaaaaaaaaaaaaaaaaaaa and more or less instantly fails you. otherwise, pretty good.
it might be b/c of the latest version if iexplorer, or maybe vista, but the movement commands keep sticking. Very annoying when the walls randomly spawn death.
dunno if its just me, but i think the squires are bugged. if you speed click on the spawner 4 them, it will spawn 1 for each click, and only charge for the ones when the cooldown is finished. massive squire army makes this game way too easy.
