I participated in this year's js13kGames, a JavaScript game development competition with a file size limit of 13kb, including code, assets and everything else. My entry was Underrun, a twin stick shooter using WebGL.

Very detailed and insightful post-mortem on the winning game of the js13kGames competition !

Reminds me of Fabien Sanglard game architetcure reviews, except it's from the author himself :)

I opted to render the player character as a sprite as well, even though it needs to be freely rotated. It was far easier to produce 8 different sprites – one for each direction – than to implement a loader and renderer for complex 3D models. [...] The game never needs to rotate any geometry. [...] To make the player character rotation look convincing I build a 3D model and simply took screenshots for each of the different perspectives. I'm a total doofus when it comes to 3D modeling software, but that doesn't stop me from using the ingenious Wings3D. The result doesn't look like much, but scaled down to 16px, it doesn't matter.
