I'm stuck at buying a leash for Yuki cuz I can't find that leash anywhere, and I can't proceed Chris' story! I also downloaded the script you posted to replace the script in the game folder but it didn't work!
The leash should unlock in the shop, which you can find on the phone, after Yuki's fifth level. Did it not?
And what's the problem with Chris exactly? Where are you stuck?
Also, you shouldn't use the old script file. If you replace it on v0.15 it will downgrade your game's code back to v0.14
-nevermind-
What can I do then?
I was wrong, you need to fully complete Yuki's story and upgrade your device to progress. It could probably a bit clearer about that.
