I would like to get to island 8 and I'm wondering, does the sun just tick down at a constant time chasing you as you fly (therefore you want to fly as fast as possible)? Or does it speed up as you get to later islands?
Also, does it have a max where you can't get too far ahead of it? (i.e. if you go super fast on the first island does it actually help more than going regular fast? or can you only get so far in front of the sun?)
