Nice to see you managing to dominate, Smile. I know you're not that suck on gaming.

Seems we have slight difference again from now.
The game doesn't seem to be that random though. The gaps seem to correspond to whatever your speed is while it's being generated. Like if you go slow, the gap will be short. But if the gap has already been shown on screen, then you bump into an obstacle, then you're going to be too slow to make it.
Yeah, the gap between buildings is decided on what your speed is. I try not to hit two boxes in a row, but if you hit one you will always be able to make the next jump.
However, I really hate when you're given a window to jump into that's too low--so that jumping at all will make you hit the wall, but it's too high to make the jump if you let yourself just fall. What the game is expecting you to do is to jump before you can even see the window and make the leap somehow.
Gotta agree with these. Though in my opinion you can jump towards far gaps in not-so-slow speed, but you probably need to jump at the end of the building in
exact timing to reach another.
Plus, jumping through that window is indeed tricky to be executed. Need fast thinking and focus for that one
(I ever ended up stumbled the upper wall which hasn't really far distance with the window, what a close call).
