Hi. My name is... you can call me Kay. My pronouns are she/her. I created The Thirty Moons System. I hate horror with a burning passion, but I love playing dramatic situations so I guess I am making a horror game XP. I love ponies big and (my) little. I enjoy writing fanfiction & or erotica, drawing, I am currently dabbling in making a videogame I don't know if I will get far, but I am having fun with it so far and last but not least I, of course, make physical games, TTRPG's and zines.
So my first thought for a winter horror land is a haunted house. In My Little Pony they have a holiday called Hearth Warming. Spirits called windigos freeze everything. They are a force of nature that can not be stopped. They can be held at bay. If you give something in the name of friendship it creates a fire of friendship that drives the windigos away. On Hearth Warming every pony creates giant fires that will keep the windigos at bay for another year.
You are locked in a house that is being frozen. Every five minutes everyone has to give up part of their character. Once no one has anything left to give they all freeze. I don't know how you win yet. Short point long my inspiration is the windigos from MLP.
If you have any ideas feel free to let me know. If you need help with your game I will be glad to help in any way I can. <3
