I created a game for a game jam in itch.io & i just found out it has to be played on browser to be submitted. What are ways to convert the game to be playable through browser?
Have a look at this: HTML5 Game Development | Unreal Engine 4.27 Documentation. Also:
As of Unreal Engine 4.24, support for the HTML5 platform has been migrated out of the engine to a public Platform Extension that can be maintained and improved by community members. Documentation for the HTML5 Platform Extension is hosted alongside the GitHub repository.
