my pc has no where near the space to store a session of attemps and idk how to or if you can record demo's on the unity version, streaming isnt really an option for me either, any help would be appreciated

Regarding the demo on the unity version, you have to ask in the game's forums. But other than that, I can only advise you to clear out your storage by deleting stuff you don't use anymore or you can search on youtube on how to remove a bunch of junk from your pc
