Looks like its going to have a few puzzles which is good you need to make a snap-to feature so when we put pieces together that fit it lines them up properly some music would be nice and a bit more effects and such to raise its appeal

I understand its a demo and you're still testing it out. The one thing i'd like to stress is the complexity of the puzzle pieces. Usually, going off other games, the pieces aren't as curvy and fit in secure block like structures. In this, you have a piece like the top right part of her hair only connecting PARTIALLY. I think it'd be a little hard for novice's. Maybe you could have them lock together when they get a match?
