Hello! I am really sorry about that. I don't know why the game stopped working, (possibly due to a new version of Ren'py). But I was able to track down the problem in the code. I've just uploaded a new build which should fix the issue. :)
“There’s (no longer) a bug in your code!!”
It works now and I just finished my first ending, thank you so much for the fast reply, immediate fix, and really cool game!
Hahaha! Thanks Struess! ;) No problem!
