Rayman Legends is without a doubt my favourite coop platformer with fantastic music and great fluid controls. I strongly recommend it, it’s tons of fun

I agree, but after I tried three FOSS ones that were hard to set up and had very bad voice quality I gave up and tried Guilded which is working great. The most important feature I need is ability to locally mute people which not many apps have for some reason. What would you recommend I use?

Guilded is really similar to Discord, but Roblox bought them so you need a Roblox account to use it. It’s great for voice chat.
