Ok, I gave this a shot. Your title attracted me because it is so close to my own game's title. :P
There is a lot of improvement that is needed. I know it is a demo, but what you have could have definitely used more work, as it lacks the quality and care. I got lost after picking up Max (I think his name is) as it wasn't very clear to me where to go. Anyway, here are some of my issues:
The game opens up with you in a room. You have control right away. No anything. The beginning of your game is what will hook in your players, and lacking one will only hurt the game. You need a good start, whether it's just some text about the lore of the history of the world, a scene from the past, or a totally different setting. A good way to start I find, is to throw the player right into the action. This way, they can get a feel more the gameplay, the story, and the characters, right off at the beginning. However, it doesn't always need to be that way, but it is effective when it is executed properly.
Your maps are way too big. They need to be about 50-75% smaller than what they are now. There is just a whole lot of nothing going on, and it makes exploring a pain to deal with as you can't really see much since everything is so spread apart. The biggest culprit is the house you start in. Serena's room is huge, ridiculously so. Not only that, be it's the only room upstairs, and her parents sleep in a bed on the main floor. The main floor is also gigantic, and when you are told to speak to dad, I actually had to run a lap in the house to make sure he wasn't hiding there. The result is a lot of floor space, with nothing on it. You need to downsize this room, or make multiple rooms within the floor. Upstairs should be comprised of multiple rooms, where one of them is Serana's. Actually, she should have a room on the main floor if anything as typically the master bedroom would be upstairs. Regardless, the architecture of the house needs to make sense.
The dialog needs work as well. Spelling errors and spelling shortcuts aren't okay to use, your type needs to look professional and polished. If a character says "Okay" it shouldn't be spelled like "Ok". It is jarring and incorrect. Serana can definitely be more interesting. Responses like "Yes" and "No" are boring and unimaginative. It makes the character seem boring. I am not sure what her personality is because of it, so with that being said, I can't really give advice on what to do with it.
Each thing you create in this game needs every detail and all your effort. This definitely looks like your first attempt at using the maker, and that is okay. Below are some articles that really helped me and my own thought process when it comes to game making. I hope they can help you in a similar fashion.
