I love the idea of the Impossible run. It's very cool and exciting, especially knowing that there are like dungeons and towers towards the end. Also the music in the background made the video just that much better lol. It really got me in to it.
What I would work on would be video length. This is personal for sure, I think 10 minutes was a little long for the amount that you accomplished. Maybe try like 5-7 minutes videos. But the length is really not something you need too worry about that much, just a suggestion. I would add checkpoints to the map for sure. It's hard to watch you do the same part over and over again lol. Otherwise I believe this could really take off for you.
Another thing that I just thought of while typing this, just one of those brainstorm ideas so honestly I'm like thinking out loud right now, you could make this sort of a "scripted series" like a t.v. show. Have however many episodes, where you encounter a problem in each and make it really intense and suspenseful. Maybe an idea for a future vid? I might even try it sometime lol. Like I said just brainstorming.
I hope I helped even the smallest amount, I did really enjoy your video and I hope this series works well for you.
