How to dash to a precise location:
1. come up to gap
2. tap dash key
3. find the blue orb that uses the same color pallet as the world and easily blends in
4. make a decision to either cancel the dash or continue the dash
5. look over to the dash meter to see if the green bar is underneath the blue
6. oh too bad you spent 0.2 seconds looking for the blue marker orb, you missed the blue dash
