Hey Dark!
If you have access to your old PC, you can upload your saves to a file sharing/storage site like Google Drive, MEGA etc and then transfer the saves to the new PC (or chuck em on a USB).
Saves are located in AHITR/Game/Saves (If not you can find em in a backup folder: AppData\Roaming\RenPy\AHouseintheRift).
Once your saves have been downloaded you can transfer them into the above folders and resume.
Other than that, we don't have any saves here. We do have a save on our Discord server, pinned in our help channel, that has everything up to 7.4, not ideal but beats starting fresh if you don't have the saves.
