It's okay. Enchanted Caves with Quests every level, which was nice.

In 1 slice mode, you can get all of the blue. Slice about half way through the open space on the blue and cut the lower left corner of the red. Blue comes all the way out.
The cursor needs to be locked into the game, if you go off the screen, the game should auto-pause. I've reduced my window, closed my browser, and clicked other websites because the cursor goes of the screen.
Level10 normal, immediately attack when heroes spawn. You destroy the castle just as the dragon appears thus getting to 10000 loot bonus for him. leave your camera on your castle and let your units destroy his castle off screen. If you watch your units destroy the castle it lags the game just enough to where you can't destroy the castle before the dragon is too close.
