Nice game but i fond difficult to put the defense tour system . Using a mouse and keyboard is a pain.
Really sorry to post a negative review because the story and the characters are charming.
I never been able to get futher than the 8 th battle (even on normal difficulty), it is simply to complex to move the character and place the defense plus you have a timer of 2 min before the battle and that is not enought !!!

There is also some bugs in the game and i had to reboot ...
i dont have a strong PC but there game is not requirying a big configuration
