I dont know how in one of the parts were he doesen't make a jump and then he just goes straight down.
I remember when i nearly made a skateboard ramp and i fell but i have never seen someone jus go straight down like they have explained. Tom me and my group it just doese'nt make sense to us.
That is the bit is when he goes up the ramp and then he gets captured by the people.
