Hi there! First off, I hope you find the right people to participate with in this and yes, have a lot of fun!
I'm somewhat experienced with game dev. I published a game on here and on Steam and got several others to near finished state but then abandoned them. So my goal for this gamejam is to get over that and learn to finish projects consistently. That's the biggest skill I'm missing 😅
I'm going to do an RPG-dating sim (SFW, no nudity or anything hardcore, just some flirting) in Ren'Py, which is the engine I always work in (did RPGMaker once and have some projects half finished in Unity and Unreal but I never finished something in any of those engines). I guess my strengths are game design and making stills and animations in Daz3D (learning Blender but I don't know how much I'll use it for this project). I am not a programmer but for Ren'Py you don't really need to be, so I can handle that reasonably well.
I have zero experience with sound design and music, which is something I want to work on this time, because I want to make the game actually have an atmosphere... I'm also no good with UI, if I'm being honest with myself! So those things are certainly something where I'd want to learn from someone else...
I've only ever worked solo, but I'm open to collaborating on this one! I don't know if you'd want to form a fixed team or contribute to several projects as you please...? What would be the most fun for you to do, have you thought about it?
