Your game is interesting, definitely nice of you to promote awareness about Alzheimer's disease.
Audio is very relaxing.
I think you shouldn't be able to solve new levels before finishing the level before.
Graphics were very good, but the animations seemed a bit off, like they miss a frame or two.
Other than that, the game and the concept were pretty cool, I liked it :)
Yeah I did consider whether to make it so that you have to complete the levels first. The only reason I didn't is because for some reason I felt it fit better with the story? I was thinking that it made it seem more like the memories were fading forever if you didn't catch them in time, and that you would have to move on. Buuuut... I also allowed players to repeat levels so I don't know really what I was thinking. I'm glad you liked the game though!
