Thank you both for taking the time to reply!
I think I'll be taking a step away from horror for this project - but we will see where things end up in ten days. I like the theme for this jam. It's pretty open-ended and suits various game types and mechanics. I have a strong idea of what I want to explore in the time allotted and luckily this theme doesn't derail those plans. I've decided to record as much of my process and progress as possible with the intent of sharing a condensed version of the whole thing at the end of the jam.
I'll be sure to follow both of your projects. If you need playtesters and I'm not too busy bug hunting I'd be more than happy to have a little play at whatever you put together.
Good luck with your games!
