for those who struggle to gain exp follow my method: complete lvl1. buy basic arrow upgrade, go back to level 1 and do the 'auto fire method' but keep shooting with your castle still visible. rack up exp by killing enemies until they send no more. send a wave of hobbits to destroy their castle.should gain around 2k exp per runthrough. buy arrow and exp p/kill upgrades till maxed repeat with tougher levels for even more exp.
