(Updated Guide)
Based off of the 0.4 update, this is a great game! I really enjoyed it and would probably spend about $2-4 on it if I had to slap a price tag on it in its current state.
Quick guide for those who are struggling.
Girlfriend messages: The cake is 10/13 and the present is 7/9. These can be found by scrolling through the calendar using the left and right arrows at the top of the home screen.
Stepmom- She will walk down the hallway, turn on a light, then open the door.
Window girl - Keep your phone out
Under the bed girl - She can't be stopped until after she starts to suck you so just land your timing right. Its the DBD mechanic.
Monitor girl - Press enter as fast as you can. It is super easy if you buy the upgrade.
Tips: After you respond to your GF, you can lower your phone if needed and she will still respond. I purposely failed the maze the first time so I can actually study the paths and find the best route. (Buying the maze upgrade makes it super simple as well. I would recommend that as your first upgrade.) The top tip of your mouse is what location is based off so its ok if some of the bottom have of your cursor clips through. You don't have to rush through the girlfriend's texts. You can send her a bad reply to buy yourself some time just dont let the hearts go all the way down.
