For anyone wanting a walkthrough here is a link to a word document where I made a log/walkthrough if anyone needs/wants to use it. Note that it isn't professionally done or anything, so it might look like shit. However it should have the steps to unlock all scenes in the gallery.
[Updated to have no issues getting the hair from Elizabeth]
[Both word links below have been updated to 0.5.1](Game has been updated to 0.5.2 however no new story has been added, only monster combinations have. So the walkthrough isn't out of date and can still be used.)
Walkthrough for 0.5.1. https://1drv.ms/w/s!At-QRpkNEdPKpzb7_7DkTUgei0CM?e=Vh4Srp
All monster combinations(the walkthrough above will get all story related gallery scenes). https://1drv.ms/w/s!At-QRpkNEdPKpziM-pV0duB2kWkc?e=h2kNOw
