really cool entry, has a lot of charisma. The creatures lurking in the dark, specially the ones running towards the player really gave me the creeps. Also props for the progressive corruption of the museum, liked how it all when a bit more occult and "lovecraftian" with each loop(also, all those references :P).
Some feedback:
It really needs some sort of checkpoint system, could get past the third loop :O . Also the controls need to be explained in-game. i'm fine with voice acting, but it could benefit from text captions.
A nice entry, filled with references and secrets, it feels like it's worth many playthroughts just to discover everything it has to offer.
