There are supposedly 21 different endings. Supposedly if you play the Harem route you get the worst ending. SPOILERS, if you choose to go with Megan's friend route, Melissa, you will be forced to choose either of them despite being led to believe that there were going to be a happy ending for a 3 way relationship, because one of them will die and you will have to choose which one to save, due to a force out of your control so there is nothing you can do about it. I think if you go with only one you'd be fine. But Megan will be force to be your date no matter what. This is what I dislike the most about the game as I only wanted to do a Melissa route only. But it's a great game once you go pass it. Because the characters get a happy ending after that event, so yes there is a moment of depression, mostly because you feel sad for the girl you chose because it broke her heart, if you go the route I did, which I think is the best route and Melissa deserves it. If you go Melissa, there will be a way for you to pair the other blue haired lonely chick with the dick boyfriend and your best buddy Liam together in the end. So it's all good.
