48 hours is a lot of time in just 9 days... I don't think I could spend that much time even if I wanted to...
Viewing post in So how on earth would you know that we only spent 48h
I think if everyone here was a full-time indie developer, there would be a much smaller crowd. Indie developer can mean many things, but a lot of the time to be successful it means putting a hold on side-projects and working on the project that pays (assuming you don't make money from something like YouTube showing off side-projects). Jams like this are mostly designed to incorporate everyone who loves game development, but maybe doesn't have as much time. I would't worry! Besides, a good point was made that the best games from these art-pack videos are the ones that are made in the shortest amount of time. Just a simple and fun concept stretched out as much as possible. If someone makes a game that was done in more than the time limit, it's usually painfully obvious.
Many game jams you can't separete time for personal needs from game dev, so if you consider Ludum Dare that have 48h, if you subtract 8h of sleep for each day and 3h for others needs you get around 26h (or only 10h if you have a 8h work in the days of the jams) in total for making the game. In 9 days would be almost 3h/day.
But anyway, hope you have enough time to make your game, even if you end up not using the full 48h ^^
