Excelent!
This is the nicest defense game i have ever played!
Very nice with the arrow combinations, sound and gameplay are really fantastic,
takin' it to favorites and voting 5 ^^
PD: nop, the explosive arrow and lead one aren't the most powerful combination, it is Lead lvl3+Piercing Lvl3, just give it a try, i used that combination to get the quickdraw medal ^^
