There's a few quiet updates that I like.
1) Reset skill points: The CT2 has that, but this game and the level pack never did. It makes it a lot easier to get brilliants on one particular level.
2) Game pauses when you click on a tower to upgrade. It never used to do that.
3) Not sure if this is a bug or not, but when using spells, you can use both frenzy and fireball at the same time as long as you have enough mana to use one. That is, if Frenzy is 200 mana, and fireball is 150 mana, and you have 200 mana, you can use Frenzy AND fireball. You can't spam them multiple times with this trick, but if it's intended, it's a nice touch that keeps frenzy relevant.
