1. No more preparation time, the moment you start the map you get the spellbook shoved in your face, and when you close it. 3...2...1.. START!
2. No more breaks every 3 rounds, EVERY wave starts after 3 seconds. (So you only have 3 seconds to remove traps if you made a mistake).
3. VERY few lives (Rift points), usually under 10.
4. The strongest enemies show up in the first few levels, 6 ogres charging you after 2-3 waves, etc.
Edit: Oh, and because there are no breaks every 3 rounds, your guardians (Archers, etc) no longer resurrect. If they die, they stay dead the entire map, unless you quickly remove them during the 3 seconds of rest.

The best set that I have found thus far is the Swinging mace trap with tar pits under them and the reenforced decoy sitting just on the outer edge of the tar pits - and for bonus points you take the steel weavers and get the regenerating guardians so that the decoy will heal. If you have no ceiling space you can replace the mace traps with the wall grinders.
