i started playing it yesterday... only like an hour maybe
The game kinda plays like bastion... instead of having a couple weapons to use, you always have the sword, although you learn new skills to use... this is where the game hooked me up
you have 4 slots for skills, but you learn more than 4 skills to use.
Each skill does something on its own, but they also have a effect if you attach it to another skill, which can completely change the way the skill works.
so, early in the game i already had 6 skills and 4 spots, so i spent a good amount of time experimenting with skills/effects to find a set of skills that i liked
for instance... you are given a piercing long-range shot that deals damage in a line, but you can decide to not use that skill and upgrade another one, increasing the range of whatever skill you attach it to
Pretty cool system if you ask me.
