FlyingPigKnuckle here.
I found your game to be unfinished and a little buggy so being able to play this game was not quite there. There was a lack of lighting at the beginning of the stage so it was really difficult to navigate my way to where I am suppose to go. The grapple hook ability seems to be universally applied to all objects but that can be an issue because that allowed me to fly out of the game or fly towards an unreachable mountain. I can grapple to sides of the castle, but I could not fit inside the window. When I attack, I see my entire character's model attack rather than just the arms swinging. When I summon my sword, I see my entire character model making the sword. This is a first person perspective game and I should not be seeing my whole model's animation. The enemy AI is not finished. So after being a negative nancy, here are the positives.
I liked the wall walking mechanic and that can garner a lot of praise in the video game community given that, at least from my experience, I have never played or seen a game where such a feature was implemented.
I liked the animations when you summon the sword.
I hope to see more in a much polished build.
