What are you on to consider a feature for adding remote play to an already multiplayer game to be the only thing you need for multiplayer ? This might not be hidden at all but it’s also not what you advertised at all. Perhaps consider actual game devs might know a thing or two before thinking doing a uni project entitles you to be so consescending.

just white wine

Come on you’re going to hurt the wine snobs with this statement. Champagne is a sparkling wine, it doesn’t taste like any white wine. It’s more like a bitter Sprite with alcohol in it.

Not everything sent in PR is an improvement from everyone pov though. It might be an improvement for the contributor of a new feature they might be the only one to ever use, while it adds maintenance burden for you, more dependencies, risks of bugs etc for the community, which you have to balance somehow. Plus you might have a view on how to do things properly on your project, which needs to be communicated to contributors, which is additional work you might not have time for, especially if this is just some small side project.
