[UPDATE] v1.0.2 fixes progression bug and crosshair getting too big over time
Hope you have fun playing.
Few tips:
Physical weapons should be used for very quick hits while spells will help you hit the target from furrther away. As you progress, the further you can hit.
Theres an info button in the skills window to help you pick the best skills to level at given time :)
And as you progress, more enemies in bigger groups will appear.
