I survived... for now!
I'm usually pretty bad at these kinds of games, I think, but I did manage to win after only four tries. :)
I wasn't expecting a huge boss to show up! The speed boost really saved me on my successful run, I was about to be overrun otherwise.
The rogue/hooded enemies were by far the hardest for me to deal with. The wizards comparatively didn't seem to do anything? They were casting some sort of magic, for sure, but what that actually did was a mystery to me.
