Hi, thanks for checking out. Yeah, I mainly jumped to the UE4 version because of web support. For small games like this, there is no big difference in engine workflow through versions, apart from UI differences. Itch.io's fullscreen toggle doesn't work on the UE4 game. I can add my own full-screen button messing with code in the HTML file, but that breaks canvas rendering a bit, adds a white vertical line on the right (you can check that in my other game "Under Review"), and while I found a workaround for this, that needed a bit of testing, and I didn't have time for this in the jam.
