Keepsake is a mix of storytelling adventure and puzzle-based games, with a strong bias on the former. The story follows Lydia's arrival at the Dragonvale Academy, a legendary school of magic. When she arrives, instead of being welcomed by her best friend as expected, she finds herself strangely all alone. She then goes on trying to elucidate the mystery of what happened to cause everyone's disappearance. At some point, we also introduce another character that will follow Lydia on her journey. We felt many adventure games lacked deep character development throughout the game, and by having two characters always follow each other, we were able to address this issue.
