I apologize for any mistakes I made, this one was in a Rush.
E1, the two orbs at the bottom are circular walls that each contain spheres in the center, an invulnerability sphere in the left circle and an supercharge in the right, and a Plasma Gun (Or BFG if you wanna be REALLY OverPowered about it) and a Super Shotgun in the same order.
In order to open them, the player has to go up the stairs to the pink section, which is a rising platform in the center of a pit (marked by the black pathways to the side) that leads to lava (and if you want, a teleporter to make it less deadly that leads back to the blue area).
In order to get by, you have to you to jump (since this is doom, this basically means, run really fast) to the white section (which is lower), then climb up a step of stairs that (I stupidly forgot to draw) are connected to the next pink area, where you have to jump AGAIN to the Blue area, where a switch is located that opens up the two circles. It also creates a pathway over the pit (marked by the same borders as the pit) that allows you to go through the past few areas without jumping through them again.
The numbers are enemies. The 1's are spawned when you get on the white area and are probably cacodemons. The 2's are spawned when you press the switch to create the pathway and are probably hitscanners. The 3 is a cyberdemon who's spawned when you pick up one of the orb items. FUCK IT UP!
I wrote STRAFE JUMP over the pink and white area but you don't need to make that a requirement to get through them if you don't want to.
