4/10
It seems that my biggest concern with the the game has already been addressed: romanticizing serial killers. The whole gimmick of this game is to seduce serial killers but the characters have names that reference real killers that ruined lives. All you need now is to add the guys who shot up Columbine and Casey Anthony and you'll be all set. In all honesty, it is sort of disgusting.
The developer says that they will change the names which is all well and good, but then it leaves the characters being one-dimensional anime harem tropes. You get smart girl, lolita, horny, tsundure and straight guy. If that is what you were going for then this will continue to be a one-dimensional game with killers and rhythm games thrown in.
As for the rhythm portion of the game, it felt clunky where instead of the usual 4-key pad we had to use 5. Pretty unusual for a rhythm game. The instructions for reaching the boosts were complicated and didn't seem to specify as to why the boosts were needed in the first place. The songs were too long for my taste and seemed like a added ploy to attract players to this game.
The art was good and that is what drove me to play the demo in the first place. However more could have been done in terms to character designs. It looked like the characters that had more detail and personality were the designer's favorites, while the less favored characters got the bare minimum or were rushed.
Since this was a demo I didn't get a clear cut of the story. Obviously as a dating sim you want those spicy bits but some of them seemed too forced. The dialog wasn't that entertaining but I'm chalking that to the game being only the demo.
Overall, this game can have some potential. But these characters obviously need a re-write so they can be just a little bit more interesting than 'horny goth girl who wants to kill you'. At the end of the day, it is an interesting concept: seduce serial killers. But at the same time it also adds to the growing culture as seeing these killers like celebrities or even having a romantic feeling towards them. It's on tumblr, you know what I mean.
