Hello! Glad to hear that you had fun! Regarding the file size, I suggest to download the itch.io app, as it means that you will only have to download the 2GB file once, as all other updates will be added as patches. I have been trying to trace the source of the massive file size for a while with not much success.
In the zombie mode, do you want the flashlight range to be longer, or the night shorter? I am doing a zombie update (which will be released soon), so this information will be useful in trying to balance the difficulty.
Thanks for the feedback!
