The idea was great. Though a few critiques:
I noticed that you had something of a contingency measure during the parkour to make it so that the player doesn't overshoot. But maybe because of that, when you jump directly from the platform, the jump feels slow. So, to reach the next platform you have to get off the platform and jump within that time frame. This made the parkour a little harder than it needed to be
Other than that, the way you made the cinematic-like scenes were great. Overall, it is really good considering it was made in a week!
