Probably sound like a broken record constantly recommending rich, but the power up does genuinely make a ton of these later UL stages much easier to work with. This stage gives you a decent amount of money to work with, and you can pretty much spam throughout the majority of this stage. Slapsticks and Jelly are going to be the main units that juggle those peons and ensure that enemy Doron doesn't grant the enemies a ton of ground every time he comes onto the scene. I like using my own Doron plus an Idi in order to take down the Othoms. I did screw up near the end of the stage with a badly timed Doron, but Idi was still good enough to take down the Othom. You could DEFINITELY play that part much better.
