since most of the levels are easy but some are a bit harder you don't find yourself stuck on a level too long. You don't get too frustrated, cause you always other ways to do it. Needs more levels; or better up: level editor.5/5
+if you want to see strand level pack.
finally got the hard badge. Level 17 was the hardest. Other people hated amazons or ninjas. But through these last hours my real nightmare was the divers. But I give them a nightmare too, by using and drowning them.
Tip: most scroll can be helpful to slow down enemies, make ninjas and iron guards vulnerable, or just deal damage. For example I saved for lightning scroll for the archmage and those made him lose 60 % of his damage. Ninjas as chickens are very easy to deal with. Since gold picks up itself only use the rest of the drop when you need it. And never let your mana fill up fully. Then you cant regain and could therefore lose a lot of chances to use spells later.
