Thanks I'll give it a try.
Hey if you find better ways for a level to level transition and include them in the game I'm the last person to complain about it. :)
One transition I like for example is the one right before the final boss. At the end of E5M3 you see that tunnel that you have to enter and at the start of the final level E5MBOSS you start inside it. Both levels feel connected that way.
EDIT: Just checked out the beginning of E2M3 real quick to see how things feel with the powerup effect being off when activating it. I like it. You still notice when it's active due to the red aura embracing the character while the rest of the screen just stays normal. Much easier on the eyes (at least for me). Very nice to have this option included.
