Yes, something went wrong with uploading so it no longer turns night. There isn't a lot to do in the game, sorry

It’s a breaking bug, so… why don’t you ask to the owners if you can upload a updpated build with the hotfix?
And… it’s a Godot project, right? you can export a web build (rename the main file as index.html), pack in a .zip and upload to itch (and mark as playable on browser… and set the frame dimension)! =)
