The Heart Attack was ported to HLM5 through Game maker Studio 2. I was a support programmer brought on later to help finish the port before its deadline. 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 The Heart Attack: a small notgame/game poem about two disparate lives that collide in war. Takes about five minutes to play through, and requires no gaming skills"
The port is playable at the link below on Jordan's Itch.IO page
