I'm currently experiencing a bug where the heat mechanic doesn't work. It will reach 100 and nothing happens. I have tried it on my main save and on a new save and it just doesn't work.
I'm on the steam version and it's the latest version.
there is a quick fix to this, i dont know how it works exactly but you need to make a text file inside game folder with a name "patch"
you place that "patch.txt" here C:\Users\user\AppData\Local\HoleDweller
