Cuphead

Each world in Cuphead has 1 chortcut that will allow you to skip a large amount of boss battles and level and work your way directly towards the last boss of the area. They are as follows:
World 1 (Inkwell Isle I) - Available from the beginning. Next to the Goopy Le Grande boss, follow the path next to the river, going underneath the land bridge and getting to the other side, ending up at Cagney Carnation.

World 2 (Inkwell Isle II) - Complete Baroness Von Bon Bon & Funfair Fever. Now, go towards the birdhouse at the top and you can walk under it and behind the mountain. Follow the path along the back to end up at Wally Warbles.

World 3 (Inkwell Isle III) - Complete Rumor Honeybottoms. Now, walk upwards towards the crane. Walk through the fence behind the crane, around the Junkyard to end up at Sally Stageplay.

You can get this achievement at the beginning of the game. Go to the right of the "RUSE OF AN OOZE" boss battle and you'll be near water. Follow the path and go underneath the bridge. Move cuphead behind the screen and on to the other side of the water.

Here is the fastest way to get this achievement!
