There's a plugin that might work for you even though it's outdated, has a bug or two (you have to make the box size larger if you're using small resolution and scaling up), and since it's not a default C2 function not supported on the Scirra Arcade section of the website.
You just have to make your own font imageset, or find one you are allowed to use.
Although personally I think webfonts would be better as you can also use it on your website as well, but I don't know how to make them or convert raster fonts (sprite fonts) to them.
Edit: Your post inspired me to look into it again.
Found that FontStruct provides a web based interface for font creation, and allows pixel monospaced fonts.
It's also compatible with FontSquirrel Webfont Generator to convert it to a webfont
Fontsquirrel seems to be having issues with Fontstruct. I made a font and used Font2Web.com to convert it. I it came out pretty good.
