I cant't describe how happy your comment made me !! I'm so glad that you liked the game so much!!
And thank you very much for pointing out the typo! I can't believe I missed that lol. I will correct it asap!
The reason why you're getting Zach ending is probably because you still talked with Yuki. To get ending 4, you have to talk to the old couple only. I must warn you tho, there's nothing extra to it, and it actually is more like a placeholder ending I added. It is to make sure I have an alternative route where the player could meet the neighbors ( Yuki and Zach ) in a different way. But because I wanted to focus on the main route first, I made that one an ending so as I could deal with it later lol.
omg I'm so dumb, I realised after replying, that you can only get the kidnapping endings only if you don't talk to Yuki at all.So I'm not sure why you aren't getting ending 4. It was working well during testing. Thanks for telling me about it! I'll make sure to check it out.
Again, I'm very grateful for your comment. Thank you lots <3
