Yeah, the combat can get very repetitive and monotonous and is well draining. There doesn't seem to be any pacing or great variety in the game, just kill kill kill with a few force pull or push this block or platform here or there puzzle moment. I try and make a point of using as many different attacks as possible rather than just utilising the most tested and true attack against certain enemies, otherwise it would get really really tiresome. The boss fight with the massive creature, the Gorog, was also frustrating and repetitive; dodge, jump, lightning, dodge, lightning, dodge, jump, lightning etc etc and as this reviewer said well outstayed it's welcome.
I haven't finished the game yet but I foresee many of these observations remaining throughout if this review is anything to go buy.
