So sorry about that! The current demo is mainly focused on testing combat and level design, so we haven't fully integrated the story into the gameplay yet. We thought that for some players, collecting all the artifacts might impact their experience. In the full version, though, the number of artifacts you gather will determine the power of the final hidden boss. Also, you'll quickly realize that Vivian isn't exactly a good person, and there's a huge conspiracy behind everything. Whether or not you collect all the artifacts will decide if the main character can stop the tragedy from spreading.
