Mozilla sponsored this week's Humble Bundle. The games are all desktop games that have been ported to the browser with
asm.js. I had to switch over to Firefox to try out Faster Than Light, but surely enough it booted up and was playable in a flash. Amazing.
I've fooled around with
asm.js a bit before just as a proof of concept to see how hard it is to port an arbitrary C script I wrote to the browser. Quite easy, and the performance speaks for itself:
For reference, the compiled C Script runs in 87ms.
