Once you're skilled enough, make your way up to where the Grapple upgrade was as Trace and then look up and right to find a hidden pathway in the ceiling. Next, head up, and then back all the way right to find a door in the ceiling to go through. Climb them, then push the big box, then let it slide back. This one's just as hard as the last one, so drop down and have fun! Pretty hard to use, not usually recommended, but oddly effective against the final boss due to the explosions. Once the boss is down, head left and use your Drone to pick up one of the best upgrades in the game: 3:Drone Teleport. To your right, the bridge will appear, and you can get to the next section.

It also lets you go through walls that are two blocks wide and even lets you go through ceilings and floors, but those have to be only a single block tall.
It lets you phase through walls by running up beside them and then double tapping the direction of the wall and holding that direction. You're perfectly safe from all attacks if you wait on the second highest pink block. Get it and head left into the next room. Head up to the top right doorway and enter it. Laugh at the silly puzzle and just warp through.
In the third door on the right from the top you can find a new power up. After a little walk, you'll find yourself at the doors of the surgery. Once you input the code, the glass wall will come down, and you will be able to access the Corrupt Cube. Drop down all the way and head left to find Elsenova.

While the majority of the achievements will unlock through natural story progression, there are some that you may miss along the way.
In the next room left, you'll immediately see another spot for your Drone. It will kind of float around in a weird pattern, scream, and then stab its stinger or lob a couple purple blobs forward. He goes back and forth along the top of the screen and switches between two attack patterns at set intervals. I will add video walkthroughs later. Use them to climb up and left. The one you just destroyed, 2. If you did it right, a bridge should emerge, cross it.
Make your way through the next couple straightforward rooms, glitching the lava? Head all the way right and look up to see a path for the Drone to take.

There are 4 achievements for completing levels without a single death. Once you destroy all 6, go back to the room. You can De-phase the black ones and Destroy the orange ones. Use Play on it, and make it reach its destination. Once you reach the bottom, go down a couple rooms and then follow the path here, drilling as necessary to reach the best upgrade in the game: the 6:Red Coat. There will be one part, where you'll have to use Play on a wall, but you should spot it easily.
Final Boss: The Flamethrower helps a ton here. I'd suggest you to go for Destroy-ing the orange ones, because they can follow you, while the black ones just choose a spot for impact. De-phase the door, go down and get the Play Power. After that, pick up the cube from the counter, and leave the inn. Xedur Hul: This fight is entirely optional, just run past it.
