I unzipped the folder, then ran "Mystic Manor.exe" and it gave me an error reading "extract failed." It made a mystic manor folder with the audio folder with 3 songs in it.
I redownloaded, and retried with the same results.
huh, thats weird. the exe is essentially a barebones installer for the game and its assets, maybe its a storage issue? sorry, ive never really ran into this issue myself :(
