A Brief History of Cambodia was ported to HLM5 through Game maker Studio 2. I was one of the main programmers on this port. The final product plays identical to Jordan Magnuson's original game developed for Adobe Flash.
Jordan Magnuson description of the game is as follows "Today I'm releasing an HTML5 port of A Brief History of Cambodia, a small "notgame" about the grim history of Cambodia. Takes only a few minutes to play through, and requires no gaming skills"
The port is playable at the link below on Jordan's Itch.IO page
