Sly 1 level skips list updated.

Paris - you can skip the tutorial level by doing a jump from a ledge to avoid the death barrier.

A Stealthy Approach - can fly to the end by using the same strat like in Boneyard but not viable, a big part of the level is skipped with sign proxy.

A Cunning Disguise - stuck spot proxy skips the level.

The Gunboat Graveyard - guard attack animation can be used with roll to fly to the end level trigger. This is also used towards the end of High Class Heist.

A Rocky Start - guard attack animation can be used to fly across the level with standard roll and invisibility, a big part of the level is skipped by using binocucom or non abilities.

Boneyard Casino - can jump into a specific spot where the water and void plain meet in order to trick the game into thinking sly is drowning in water inside the void which causes him to sink downwards to then get sent back upwards from the void to his last known grounded position with all the speed allowing him to fly up past his grounded position to bounce off the corner of the pillar and fly to the roulette wheel.

Two to Tango - can fly to the end by using fast and moving invisibility in a corner on PAL.

Straight to the Top - has a level skip proxy spot, you can also use fast and moving invisibility to proxy off the arrow sign at the beginning and land directly on the wrecking ball.

The Lair of the Beast - going out of bounds skips most of the level, can also use a tree branch to jump towards the end level trigger.

Piranha Lake - can clip through a precise spot next to the gate to skip the level.

A Grave Undertaking - going out of bounds at the beginning basically skips the level.

Descent into Danger - can jump far enough into the water tunnel from above to skip the level.

A Perilous Ascent - can fly over the gate by jumping into a specific spot in the water and roll bouncing off a snow mountain to skip a big part of the level. This trick does not make use of the void like in Boneyard.

The Unseen Foe - invisibility proxy spot, skips most of the level.

Rapid Fire Assault - can skip the level by spinning in a corner to get out of bounds. You can also get on top of the pillar afterwards to collect the key.
