1. I'm Stern (Felix is my anglicized and online name), avid homebrewer and storyteller, though not much actually published
2. I play both oneshots and longform on a regular basis. For oneshots, I prefer simple systems with a strong weird flavor and ample room for improv. For longform I mostly use D&D 5e, but looking to expand.
3. First timer on a jam, but I have designed and written plenty in the past
4. Actually publish something. I will at least have a finished Inside Out hack/expansion of Lasers & Feelings and hoping to create another original one page rpg with others, so hit me up if you are interested
