Hi! Yes, all submissions must be browser playable for this jam. We have a suggestion in the jam FAQ that may help you to export Unreal games for the web but I would check with experienced Unreal developers before settling on that. Otherwise the only option I can think of would be to test what you've learned so far with a quick dip into another game engine. If you drop by the jam discord and say hello, other devs may be able to help you choose an alternative.

Thankyou for the reply! I do have interests in another engine later down the line but I honestly don’t want to overload myself with too much information so I think experimenting with another at my current level isn’t wise yet. I will reach out in your discord before the jam starts and see what assistance I might find, otherwise I might have to skip this one for the time being.
