Playing the test versions makes 0 sense. The bits of new content aren't worth the trouble. There are bugs all over the place, you never know when a scene will have missing buttons, causing you to be stuck there, with alt f4 the only exit strategy. And since there's no autosave, you can easily lose hours of progress, which is super frustrating.
And the bugs aren't only in new scenes, since the dev did a major rework of internal components, any scene could potentially be bugged (in one of the test versions, I reported the very first scene you could do at the start of the game, trying to enter the bathroom becky is in at 09:00, as bugged).
If you aren't playing for the explicit reason of finding bugs, you're just gonna end up frustrated sooner or later.
Sharing buggy broken test builds benefits nobody.
