Pretty interesting stage. I prefer using rich here because it makes the startoff just way smoother with the cash, although that didn't stop me from dying to it the run before lmao. Your focus is wiping out pretty much everything at the beginning, and luckily, two Cerberus Kids come out a bit later so if anything doesn't get cleaned up by Corrupted Peng's surge death, you should be fine. From there, you can just kill the Cerberus Kids off with boulder, and wait until your money is max.
Once you hit the base, it's pretty much a game of spamming everything except Idi. Get as much Slime value in as possible while the stage still provides you with peons. This is going to be helpful for chipping down Othom and Mooth once they come out. My strat to kill Othom is to wait for the Midnite D's to be knockbacked, then use Doron + Idi to take out most of Othom's health. Wait until the Mooth is dead so you have sufficient cash to pull this off and still have some remaining to fund your other damage dealers (plus, it'd be pretty annoying if Idi attacks Mooth instead). Once Othom is dead, you're definitely not in the clear. Watch your cash carefully, and try to snipe the Midnite D's using Bullet so you minimize the number of knockbacks they can rely on. Stalling becomes significantly easier once one of them is dead, and you're in the clear once the other dies off as well.
