lol are you a troll? the game works perfectly without any bugs, it has no dungeons and the gameplay consists of walking and running, I don't understand how frustrating it can be .. if it crashed it can happen I'm sorry but it depends on other things on your pc probably, it never happened to me and I tested it thoroughly ..
i worked a lot on optimizing the memory to keep it low without ever showing any loading, but i don't know how people start games, you should close all other programs before starting the game etc.
however if you really have encountered bugs be more specific please so I fix them,
as I said to get the other ending just go to where the crying man is to find the secret zones,
it is not necessary to understand why just listen to the sensations, if you don't like it ok no problem but don't say false things please :)
