Hi Barrelcat!
Thank you for your kind comments, and I'm glad you enjoyed your playthrough! I've had a couple of other folks tell me that they've successfully obtained more than 1 ending; are you using the mac or PC build? I'll play test it on my end again to double check for this glitch/error! Which ending are you landing on over the over again? Is it ending 9? The other possibility is that you may have not chosen the "appropriate" combination of choices during your play through (it's pretty specific), and if you want, I'm happy to give you hints/pointers re: how to get the other endings :)
I use a PC and I do get ending 9. I've tried a few other choices but I usually still end up at the drink club without the choice of being able to choice a drink, to which I'm sent home and then I receive ending 9. Was not having a choice a part of it? :0 Maybe I just suck at this xD
