Excellent TD! A few critique points though. Ninja Champions are really annoying, especially since the preview of the waves is relatively short and you don't know what endboss to exprect. Brilliant is hard, I like that. Keyboard shortcuts would be nice. W = upgrade, Q and E for upgrade decisions. ASD for spells. More fun and polished than Gemcraft but could use more levels and some more differentiated strategies of the former game.
What I really hate about this chapter are going from the left-most screen to the right-most OVER AND OVER. If the bees weren't bad enough, SIX times (or more) for the colors? Come on! I liked the previous two chapters much better. 3/5
