I'm attempting some of the fixes, but it still freezes. I'll continue trying though, hoping something works.
In the meantime, is it not possible for you to upload the 4 cutscenes somewhere? NewGrounds, Patreon, Dropbox? I would not mind going through another paywall if it means I actually get to see the cutscenes. Just as long as it isn't Subscribestar, because that platform doesn't work for me :/
