Excellent, and very addictive.
I really enjoyed this game, and it kept me hooked for quite some time! These kinds of round-based defence games are often quite addictive when done well... and this one was most definitely done well.
The upgrades, enemies, weapons, trophies, and medals were all spot on, and furthermore, it was an amusing premise for a game. Evil bunnies! Brilliant. I especially enjoyed the little cutscene where the woman (whose name escapes me at the moment) dies after a bunny bursts out of her chest, Alien style.
