All you have to do is wait forever that a favourable configuration appears by chance. The position of the escape spot seems totally random, while it is what makes a level actually hard or not. Overall I'd say the idea is great, but the details and maps need more work. 4/5.
The normal mode is boring ... gets to easy as soon as you have enough traps. I found the monstrous mode just difficult enough to be fun all the way till wave 30. Overall simply a great game ... CONGRATS BERZERK !
Pretty cool game ... I got "brillant tutor of combat" tier 5 (130319). Couple of weak points though : the difference between carreers is pretty inexistent, and the combats are lame.
I really enjoyed that ! There is no stupid endless learning curve before you can start to play with many powers & combos ! It is true that the saving mechanism is a bit annoying, but it spices up the game too. Great job !!
