Here's another version update to fix some small flaws!
Now you won't receive infinite daggers (lol), the piano room is locked while the countdown is active, the cold doorknob door works better and some other small things are fixed. I removed the plugins that may have caused issues too. 

The old versions are still playable, so if you downloaded them you should get to the endings with the walkthrough, but the new updates have improvements of some mechanics too. Of course, if you discover other bugs don't be afraid of pinpointing them to me, your feedback is very helpful to me!

A big thanks to Cicada Human, Gianmher, CuteRadish and Mimi for the feedback and the suggestions!
