Did you try using chrome? I know that there's some configurations either in Firefox or Chrome that allow you to extend the amount of memory usage with Unity WebGL, but I'm not sure which.
In any case, I'm a bit short on time, but I'll try to add a downloadable standalone version in the next few days :)
Hey it worked! =D Thanks!
Can you get the downlooadble version you said?
Its not working no matter what i do
