The movement of DUSK is fairly simply and fun to utilize, and will assist you in your speedy endeavors greatly.

First thing to know about the movement, is that there is a hidden speed multiplier that you can raise through consecutive jumps while holding certain keys. In order to gain speed, you must be holding a forward and strafe key (ie. W + A, W + D, S + D, etc) when you jump. You will lose this speed multiplier when you are back on the ground, so keep jumping!

You can buffer jumps in mid air by letting go of the key and pressing it again and holding it down, this will make Dusk Dude jump again as soon as possible and incurs no speed loss when done correctly.

The speed bonus multiplier starts at 0 and caps at 0.8, with each jump incrementing the multiplier by 0.2, or 25%. Every frame you are on the ground this multiplier shrinks by a small number, returning to base speed after about half a second. This bonus is hard capped and beyond normal speed + the bonus multiplier, any extra speed gained from explosions will be very quickly reduces back to the hard capped max speed. So while you can get some speed boost from rivet shots, they are only micro-boosts.

Bonus ladder tech: You can also use space to launch yourself forth from a ladder at much higher speed than normal, but as previously mentioned you quickly lose this speed bonus. Still makes a notable difference and should be used where manageable.
