I'm assuming you don't want a walkthrough, because those are readily available, but just some pointers.
I use nothing but artillery and mage towers, aside from one set of palladins, on Rotten Forest. As long as I don't get too impatient with calling waves early, and as long as I don't misuse Rain of Fire, these do the job very comfortably. If you start with a fully upgraded Tesla tower, the various spiders, Husks, Necromancers and Demons (except Demon Wulves) don't pose much of a threat. Hence don't worry about the magical resistance of spiders and demons. You don't need archery towers.
The Treants can be dangerous because a few spawn near the exit, and also just through shear numbers. Numbers + high armour implies that Sorcerers plus Artilerry is a good idea. A bit of crowd control right at the back (e.g. one set of palladins and/or a couple of Level 1 Teleports) is also helpful. Use Rain of Fire on large crowds, but don't let your Teleport screw that up. They also have enough HP to be an okay target for a Level 1 Death Ray.
Swamp Things are potentially very dangerous. Don't let them sit there attacking your soldiers while receiving no damage. Place your soldiers right at the back of their range, and move them forward only once a couple of Swamp Things start using their ranged attack. Also use Tesla towers to ensure that Swamp Things continuously take damage, even though they're rarely at the front. Beware of their regeneration. This is why they're bad targets for Rain of Fire unless they're already at <50% HP. It's also why you should only buy Teleport once you've built enough towers that a teleported Swamp Thing will keep taking heavy damage. Level 1 Death Ray is great against them, obviously.
The only other enemy I give thought to is Demon Wulves, because one can sneak through. This is yet another reason to build Tesla towers, and you can also use Rain of Fire on a combination of them and Treants. Be ready to place reinforcements immediately afterwards because your soldiers may get wiped out by the infernal combustion.
So at the choke point I build Tesla - Paladin - Arcane - Arcane - Tesla - and spam fully-upgraded artillery and unupgraded Sorcerers after that. Hmm... actually that's not quite right - I build one sorcerer tower quite early: just in time to greet the first Treants near their entrance.
Gerald or Malik are well suited to the level, although I have done it on both with Alleria and with no hero.
