I was wondering if a Pro License prevent assets from being used in Html 5 web games.

yes, i am

@topijerami

Yes, as in it prevents you? (which was the question)

Or yes you can use pro license assets in html 5 games, you are?

I had the same question been asked a while ago ,
to my knowledge and understanding of the current license, it allows for usage in html games. 

Why do you ask?

I bought some nice pixel art a couple weeks ago because I’m working on an Html 5 game for itch (personal project, free & non-monetized). I then read the conditions of the Pro License and realized some of the terms a little vague when applied to something accessed over the web.

Just want to make sure that I am compliant to the license before I finish my game and release it.

Well i suggest you contact Gamedev Market directly if you want to double check your case, good luck with your game!
