Go through the door on the left. Jump the train and go left. You'll see a parcel inside some collapsible floor. That's a powerup
Now go right, back through the door you came and into the room you posted. Now you'll find that moving ladder is climbable! That's what the first parcel enabled you to do. Collect the parcel (this one lets you use warps) in this room as well and any parcels from now on for that matter, you need them all. Jump the three blocks to the right. Grab the oil to replenish your health and drop down onto the little white nipple on the ground (N.B. Be sure to remove the end piece of collapsible floor above it or you will be trapped. Welcome to Thing on a Spring
Go to the next room on the right. Pretty easy room. There's oil you can reach by warp nipple. There's a parcel in the middle of the room that's needed to use the lift. When you've finished it's time to head back left through all the rooms you've visited. There's only one new room on this floor which is easy enough. There's a picture fragment above the door in this room which is only important if you want to complete the game. Ignore it for now. Head for the exit. Through the next corridor is the lift which you can call by pressing fire.
Right, I've held your hand enough already. You're on your lonesome from this point. Good luck 'cos its a cunt of game
