Still lots of thing you've missed. You have freeze or normal, but that's all. And enemies should be able to take more than one path per wave, are a few. Furthermore, options for making enemies are small.
The only thing i dislike is how bad Veradux is: he doesn't heal when you put him in Phalanx mode a lot of the time, it's hard to get his stats up to a decent level, but you need him for healing >.<
