QUICK HINTS:
DO NOT upgrade the training ground (they provide less point per tp)
DO NOT sell the E weapons (the have the best dps as weapons)
To beat the boss max out everything from the best grade BUT use one E weapon as your dps weapon and the boss is good as dead :)
Amazing how a game can be unbalanced. first training area 2:2(points:price)=1 then goes down to 3:4=0.75 the up but not back to 4:5=0.8 why?? weapons E 50:1=50, ~100:2=50 then weapons D ~160:4=40 why everything goes down? sure it's more att and all but it's so unbalanced.. +boring after class E. 3/5 is kindness :/
Why when pressing the "quit" in the middle of a game the question says "Do you wanna continue?" instead of "Are you sure?" (made me lose..). Also there is no 'pause' or 'quality' buttons.
