How far can you get on orcs must die 2 endless mode

Playing the level ‘the tower’ I am able to get past level 60, but I end up committing suicide by jumping into the lava out of boredom at that point. I could’ve easily gone many more levels. How far do other people get?

I’ve got the achievement for surviving fifty waves, so I know I’ve done at least that much. Not sure if I’ve gotten to 60, though. Eventually, the trolls are too hard to kill.

If you set it up so your floor traps are a mix of mushroom spores and floor portals that makes them easier to kill.
