Well, here are my three favorite slices. I know, three is a minuscule amount, but three more randomization options is better than none. I figured my few favorites would be better than a glut of generic stuff. One of them is an exterior slice and two of them are boss rooms.
Boss rooms were the one area in which I noticed the most amount of recycling in terms of design and the amount of times I saw each slice, since it's somewhat difficult to make a myriad of rooms you face the henchman in without running out of alternations. Some of them are also fairly easy when you can shoot out a row of crates and hide behind the rest. That's why I wanted to add a couple more boss room options for the RNG.
Anyways, here they are.
