cold be better
it need improving!
need balancing on the spells.lvl 1 spell upgrated are far more powerfull than lvl 2!
and you should draw a better fild and make more nice effects. and turns the spell more interactive...not just clik somewhere...something like aiming the firefall or make the tunder take some time to charge, so we would need to calculate the time till the enemy enter that spot where the thunder will damage hin! and things like that...
or make fun things like:using a fire meteor skill =. you select it. then a big circle showing where it will hit show up ...you clik where you want it to fall, then she starts charging it...for like 3 secs then she is free to do anything, but the meteor will only fall in 10 secs.
would be fun being like that.
anyway good luck improving it ;)!
