It starts Saturday, 2am here. I have a meeting on Saturday, so it's pretty stupid. I might join the Jam, but I have to work on monday. So, I think my plan is:
Sat early morning: think of a theme, start prototyping.
Sat evening: code-monkey
Sunday evening: finish stuff to make it playable, make levels if required.
Either submit, or, Work on Monday evening on tiny stuff.
.. I don't think I have a real chance to bring a proper game, as it might sum up to <12h of coding time for me
I hope to be around for support, though.
