VanishedOne: She goes back to normal after you click on 'her'.
Actually, I recall another bug where she'd lose her animation and be standing like a scarecrow, but I can't remember when (even in which episode) that occurred.
Thanks for your responses.
jcoa: Fist Puncher has Robot Unicorn as a DLC character in Steam only, and Hatoful Boyfriend also has some bonus items only in the Steam version.
fronzelneekburm: As for Hatoful Boyfriend: does the regular Steam version come with those extras or is it just the (slightly more expensive) collector's edition?
If the latter is the case, then it probably won't go on the list. Sure, it sucks that we can't have the complete package, but in this case, I'd understand GOG's/Devolver's (or whoever else made that call) reasoning. After all, whenever a game was released which offers bonus content DLC, the community has always been quite vocal in its (IMHO misguided) outrage!
Looks like the extra stuff on Steam is only in the version that costs $5 extra, and I don't think that version is on GOG.
