Haha I jumped just as I leveled up and it just stuck there with me spinning in the air and then I paused and unpaused and now it's stuck zoomed all the way in and it skipped the level up >.>
I beat the last level. Where people usually have trouble is at the zombie space walrus. You have to start with his LEFT tusk. It seems counterintuitive, but it works, I promise.
Don't bother playing through on an easier difficulty before insane. You'll get experience fast enough that it won't make that big of a difference anyways(you should have finesse maxed by a little into level 2). And don't waste your time with anything but finesse.
Actually, that scene just freezes for me no matter what. As soon as he gets to the door or as soon as you skip, he just keeps walking and never goes anywhere.
