I did try really hard to beat this game but I end up giving up. I didn't miss any section but just didn't do enough lights

The parkour levels are pretty good, also challenging. I enjoyed them overall.
One thing that's frustrating is the checkpoint system. At some point I was completely lost (didn't know where to go after going to go at timestamp around 4:23 seconds in the video. So I just went back and try to see if I missed anything, this also resets my checkpoint to the starting area. I end up spending over 30 minutes more on climbing back up after finding out the way from the walkthrough video. I wish there's a teleport system between the checkpoints. Also some indicators to where to go. At 3:32 I attempted to go to the left instead of up and the difficulty drastically increased. It's still possible, but took me forever. I only realized there's an easier way after watching the video tutorial.
Overall I did enjoy this game, but I think some small changes will make it much better!
(Also I like the fact that this game allows precise movements like these:

(yes both of these pictures are safe zones, small hitbox is great :>
