i love the concept and the lore implications with cybin's past partner (?) and U's potential connections... i got 4/5 endings but can't seem to figure out the last one, or the non-listed input choices, including the ???? option when talking... if anyone has figured them out, please lmk!!
I just added a guide to the Downloads section!
thank you sm! ^^
this is the best yuri that has ever yuried and i will be waiting day and night for more content if i am blessed with such gifts. i will be daydreaming about this lore during long red lights. 10/10.
well I am here really early lol (will update this when I finish the game) First impressions: the art is really nice and the UI is clean and appealing. The dialogue is well-written, and the choices feel thoughtful and meaningful. I definitely plan on keeping this on my computer when the full version releases. I also love how the game is interactive with the server—it adds a unique layer to the experience (though I might be misunderstanding some mechanics, since it doesn’t seem to continue writing after the first word).
Thank you so much for playing, I'm really glad that you enjoyed your time with it!! And ty for the note on the mechanics as well, I'll keep that in mind for future updates :0
