In a humorous speech on the Monday of the Independent Games Summit, Kloonigames' Petri Purho talked about what he learned in creating IGF 2008 Grand Prize Winner Crayon Physics Deluxe, stressing the importance of rapid prototyping in its genesis.
As he noted in the speech, "doing prototypes really worked out well for me," and it also gave him a hint towards which of his seven-day-created Kloonigames freeware games would break out, based on download counts.
He averaged 2,000-3,000 downloads of his previous prototypes, until the Crayon Physics prototype did around 25,000 free downloads in one month, and increased again to 250,000 when his YouTube demonstration of the game became incredibly popular.

I've got a fever, and the only prescription, is more bundle!

"Having only been available for less than 24 hours, the Humble Indie Bundle #3 has sold 130,000 copies raising more than $600,000 in the process. In return each customer now has access to the following five brilliant indie titles: Crayon Physics Deluxe, Cogs, VVVVVV, And Yet It Moves and Hammerfight with a combined value close to $50. How much do you get them for?"- The Stoned Sheep
That is so freaking awesome. I wish I had a Tablet PC just to mess with that
The first crayion wasnt bad, but it was pretty simple. I wonder what the full game is like.
