The game is really good, and the gameplay is quite addictive. It's a action-tower defence: you have your tower that automatically shoots and your character which can fight. There are some difficulty spikes, so it's not brainless, but the last boss is oddly easy, and it happens right after one of those difficulty spikes. The MC is a nun, which is always AWESOME, and her outfits is beautiful. BUT some animation are better than others, the main menu cg doesn't look like the MC (boobs too big), and there are few animations.
