Hi Alexandre, you do make really nice music pieces, absolutely love the "golden age of videogames" vibe! Immediately reminded me of games like Lands of Lore, Alone in the Dark, Dune 2 and Master of Magic.
I'd like to team up if you are still available (and comfortable working together).
Caveat 1: I've been developing games hands-on for only about 2 years (but mostly full-time). I'm not a pro in any field but I've experience creating a game on my own in Stencyl - design, code, writing, 2D art, sound design etc. (e. g. www.firesidehero.com, work in progress). I've previous business and games industry experience.
Caveat 2: Point and click adventures are not my favourite genre, so I was rather thinking of a 2D light puzzle / strategy / RPG-ish game with a strong narrative component, or making a weird blend of other stuff. That will of course depend on the jam's theme and your ideas, too...
Please drop me a line if you're up to teaming up! :)
