to fast forward easy holdt it with left mouse then click the right one and it will stay in fastforward

dont buy alot of sniper towers as they cant kill only lower the enemy hp a couple of %

its beter to upgrade the towers rather than buying alot of them

place all support buildings on the top next to your castle they help alot

also the first trap that looks like a prison is good

second boss stay between the hole's when he pops up jump and attack 3 times then run to the other side till the fireballs are gone run back and jump attack again if u time it good u can combo him when he gets down because he goes down with the same speed as u fall

to kill the first boss attack him till he atks then go 1 platform below wait till the fireballs are gone and jump back up and repeat

buy alot of ethers healing is beter with magic
