This felt like forcefully trying to make a speed-run in a game you've never played before! Which to be fair felt rather stressful. Though I guess, that it simply needed more enemies and stuff that you can one-shot along the way.
Not sure about the Parry mechanic. Though it did provide an element of choice, it was so hard to use it successfully with the time constraints that I preferred not to.
Overall it was a pretty cool though. At least after playing a couple of times and figuring out the layout of the map .
