Open the error console (via the Web Developer menu item) and you'll see messages there. Success shows up as "Error: successfully compiled asm.js code." :-)

P.S. Looking at your code, I can tell it's not asm.js conformant yet, though it should just be a bunch of small tweaks (e.g. an expression like (a+b) will need to be (a+b)|0, etc.).

Thank you. I just updated my code and it's really within half of native speed now... (benchmarks in the README, if any of you are interested)

asm.js is very exciting technology!
