With such a simple premise, Crayon Physics Deluxe really delivers. Using physics to manipulate the world and the objects that you create, in the attempt to get a little red ball to the star(s) to pass each level. There are some amazing levels that force you to use your imagination in ways you never quite thought you would have to.
GameBlurb: "I thought it would be a good idea to set aside my backlog and play these games in the context of a sincere plug for the awesome folks who put this thing together for the third time now."
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
I first played the tech demo of the game back in 2007 (I think). It's definitely worth trying and it's a testament to the unmatchable creativity within the indie PC gaming scene.
