Pixl.js doesn't render text

Hi everyone,

I've just received my first Pixl.js and started trying it out. However, it doesn't display any text at all. am I doing something wrong? I've tried a few of the examples and everything else works fine. If I try for example the dinosaur game, it won't print "Game over" if I hit a cactus.

Or a simple example:

g.setFontVector(40);
// Draw a pattern with lines
g.clear();
for (i=0;i<64;i+=7.9) g.drawLine(0,i,i,63);
g.drawString("Hello World",30,30);
// Update the display when done
g.flip(true);

The attached screenshot is what I see on the screen.

Can anyone help me?
