It is still doable (I think last time I played without Quick Freeze I reached close to wave 100 or a bit above?)
Tips:
- Use Ember Demons as Meat Shild
- Use WormHole on Boss Waves (to either fight them at your Core or use Apocalypse. Recommended Colossuss and Democorn)
- Prepare Assabmble Ritual - Prepare Uprising Ritual (have a large Crypt near your figthing points)
- Convert all minions you can get (especially Chunders)
- Have a huge Foundry (to easy and instantly rebuild defences)
- Have a huge Barracks (and have a Tavern near by)
- Rebuild Defences manually (your workers need too much time)
- Try to Micromanage as many things as possible for you
What I can tell, you have to improve to reach it. And Micomanage more stuff, and use those Aspects you have in a creative way and combine them, also rebuild defences ASAP, If there's a lack, at Gateway 2, they will destroy your Defence line.
Also, you should understand that more Rooms Props means more Minions (for Beast Den: Bigger Beast Den = more Beasts), and train your Minions (use Barracks, Wisdome Juce and the Arena at the beginning or in between breaks)
What I can tell, sentinals and Vampires aren't worth it. Minions or Defences alone won't hold the enemies back, that's why you should drop at hard waves to your defences.
