i dunno bout the save sphere reset thing cos i personally never tested it, i'm just going by what it says in the guide. i don't think it's necessary anyway. we'll just settle on a difference of opinion :D
the last time i played through this game i got the sun sigil on my 3rd attempt. i agree that it is based on luck but only for the first stretch down the ramp, in that the 6 balloons need to be on ur side of the ramp. if you can get all those first six it's not too hard to get the necessary amount you need. jus take the path with the most balloons on it (or the path the trainer hasn't taken if she's in front) and don't go for a balloon unless you're 100% you won't get hit by a bird in the process. getting hit by a bird actually adds like 5 seconds onto ur time because you stop for 2 seconds when you get hit.
btw, i love the fact that you referred to me as not being human! :D if this is the case then endless must be some kind of earth bound deity!!!
