There will be a happy, true, sad ending with pretty different outcomes. And two short epilogues to every of those with a more positive, and negative one, so 6 of them.
I don't want to spoil them here though
I'm looking forward to them though as I'm curious how they will feel to me when I play them. Don't know how it is for you, but I really enjoy playing my game more than any other VN
So I'm probably the one looking forward to new content the most.
And noo.. no Ellie zombie pet please <3 She's too precious for that. Though I'll probably cry over the true ending.
