The theme for this jam was Music Video Games, to come up with a game idea based on or inspired by a song (note: not creating rhythm games).
A little girl goes for a walk. When the sun shines on her, she is happy and spreads happiness to all those around her. When she is in the shade, she is sad. You control the sun, who wants to make the girl as happy as you can. You do so by positioning the sun so that the clouds beneath you don’t end up shadowing the girl.
Check out the Triangle Game Jam page for Sunny Day for a download and more information. We struck a compromise between the two day approach of previous triangle jams and the 2.5 day approach (meet and start working Friday night) in the Global Game Jam by meeting on Friday night to come up with ideas and teams over BBQ and beer, but we didn’t start coding until we met on Saturday morning.
