Are there any big things that I should know prior to starting it?

Most of the tricks in the wr video are fairly straightforward. I haven't put together a proper guide yet, so following with the video is the easiest option right now for seeing the tricks.

A lot of the tricks involve jumping on top of enemies (mostly the tall, dark green goblin dudes) and then over something else. Some skips involve different enemies that are all more finicky to get on top of.

Combat is mostly doing the first two attacks of the heavy combo and countering enemy attacks.

I'd recommend playing with a controller and going through the game by yourself at least once. It shouldn't take more than 4-5 hours.

If you have any other questions, I'd be more than happy to help you out.
