Hey there! I tried the demo and enjoyed it, and the game runs smoothly.
What I liked the most was the dark ambience and the enemy designs (I liked some of the noises they made). I feel that with controller support it would be even better, but the movement in open spaces was great.
What I had problem was with the weapons cycling. While in combat, it was hard to choose what weapon I wanted, and sometimes I even ended up without a weapon equiped (maybe use numbers to select weapon).
I'm not a fan of the first part, spaces were tight and you move a lot. After leaving the boat I fell into the water, and when jumping I almost could fly haha.
