Since there is also a focus on parkour in this game, the movement is way too slow to accommodate that. A good example of parkour fps would be KARLSON. However, a game like that, or any good parkour fps game, is impossible to make in a single week. I think parkour fps is generally out of scope for a game jam, so next time you should probably choose something which is easier to make, such that you have more time to polish it. However, based on what you did manage to create in a single week, I think you did a very good job.
I'd really appreciate it if you would have a look at my game as well, and be sure to download the smaller version :D
