Web Version of Choice of Kung Fu?

I’m trying to buy Choice of Kung Fu and I keep getting redirected to Steam. I don’t have a Steam account and have not needed one previously to play the other five games I have purchased (Choice of Robots, Choice of the Deathless, Deathless: The City’s Thirst, Diabolical, and Life of a Mobster) on this site.

Is it possible to play Choice of Kung Fu on the site, or am I required to buy it from Steam?

I have it as a chrome extension from the chrome web store by the look of it thats as close to a web version you’re going to get at the moment.
