the series has often been compared with the "resident evil" series and has been praised for its focus in action. however, the first two games were criticized for forcing the player to use the directional pad rather than the left analogue to make the playable character to move. this issue was solved with the third release which generated a good response. another subject of criticism is the length of each game with opinions sometimes differing due to the replay value they offer. yoshinori ono acknowledged the third game's short length and thus made "dawn of dreams" become the series' longest title.
