html, css, canvas and javascript are really fast development - I've been jamming for the past year and have been a shove stuff together coder since 1985 or so (yeah, just a bunch of not so nice code and functions thrown together). Here's something else I wrote about 10 years ago... http://lostwords.org
(( The mobile friendly source code (lost words world) is over 5,000 lines of really ugly JavaScript! )) ( The desktop game version that is also found there is equally large and includes the ability to make your own word search puzzles -- over 10 years old though, so you'll see it is a little rough looking. ;-) )
