With less than a week to go before the Humble Frozenbyte Bundle "pay what you want" sales event ends, developer Frozenbyte has added more extras to its five game bundle of new and older titles. The biggest addition is the free playable teaser demo of the upcoming platformer Splot. The full version will be released later this year for all Humble Frozenbyte Bundle owners.

The source code for Frozenbyte's Shadowgrounds and Shadowgrounds Survivor games has also been released. Finally the level editor for the puzzle-action game Trine has been made available. So far the bundle has generated over $720,000 in revenue for the five games involved along with the two charities (Electronic Frontier Foundation and Child's Play) and a tip for the Humble Bundle organizers with over 4 days to go.
