now this is what you call a great tower defense game.. im tired im hungry i played this for hours already, my eyes are hurting but im still playing it.. really addicting and fun..
currently level 21 with 4 more achievements left to unlock (master of fire, overlord 60/120, excellent 11/15 and brilliant def 10/15).. i got good in lvl 8, 9 , 12 and 15.. excellent in lvl11 and brilliant on others.. i find other levels easy and others hard.. T_T
for me, try to unlock other maps if your having a hard time finishing a level perfectly.. distribute points that are impt unless you don't care to grind until you unlock all skills.. XD
undead skills rules! crypt towers are my favorite..
btw, thank your for getting exp in this game not that hard or long.. unlike gemcraft labyrinth.. its like needed exp to level up is only 10 but you gain 0.01 every level you finish, another bad part about it is that you don't gain shit when you die.. that game aims to kill you of boredom.. unlike this game :D
