I would have to dig around my backup drive for the alpha 1 experimental builds which is out of the question at the moment with my job now. they might still be available to download on the soggy horror itch io page through the freely available app.
I wouldn't bother since its early alpha stuff that have mostly been improved and rewritten althrough not used currwntly in the thorn mansion map. They werent connected to gameplay at all with those builds and werent rightfully received well.
