full beat the game and now that i try all the weapons i highly recommend buyin chaos rather than spear
doomsday is kickass
remember to shoot through walls by standing right against them
it helps alot on last lvl
tip from todays leader in monsters killed:) :when going for glowing frame scores, always try to increase your mana pool. This increases your score/mana multiplier by 8%. This is most useful when you are starting the game so the effect lasts a long time. Theres been levels where i have doubled the glowing frame score using this method. I have often had over 30,000 mana ready to use and over 50,000 mana of storage
for the last boss i only used blue drags and angels up until he got around the halfway point of the map. then i used only angels and sometimes hobbits to provoke an attack and prevent the castle from getting closer. won with 500hp+. obviusly upgrade everything and just keep asdf held down without hitting ur own units. first try
