There seems to be some unwritten rule about writing "I'm in!" here, so I'll just have to do so as well. :)
I just found this jam a few minutes ago and might as well join, might not be able to go 100% but should at least be able to get something small done. I've no experience with online game jams before, but have attended several physical ones.
The tech will be Unity and probably a bit of old networking code I've been wanting to test out.
Now, I guess I should figure out more about what's happening here :)
I think it's an old jam-tradition, potentially stemming from LD. Anyway, welcome!
