It does have assist options if that's what you want, Game Maker's Toolkit actually made a video about it. I haven't finished it myself but it was pretty fun, even just exploring and getting the story bits and such.
Celeste is $2 right now, I got it for free on the Epic Games store but I got it again for the steam cloud saves.
I got Doom Eternal and started playing that, it's actually really good. I feel like I'm pretty bad at it but that means lots of room for improvement.
Of course Terraria is a must-buy if you don't have it already. Same with Portal and such. Stardew Valley is also really good, but I didn't really enjoy it until I played multiplayer with my friends.
Looking at the Nix package, it seems like it just enables the Meson flag "enable_gamescope_wsi_layer" and adds the package "vulkan-headers" to the build inputs. Looking at the AUR package it uses vulkan-headers but idk what meson flags it uses.
I had this issue when I was using -F fsr, you could try disabling that if you're using it. I also have to do ENABLE_HDR_WSI=0, since I have that enabled for MPV but setting it to 1 makes Gamescope break.
My current launch options are ENABLE_HDR_WSI=0 DXVK_HDR=1 gamescope -f -H 2160 --force-grab-cursor --hdr-enabled --hdr-debug-force-output --hdr-itm-enable -- env MANGOHUD=1 %command%. I may also have ENABLE_GAMESCOPE_WSI=1 set as well, you could try that.

Yes, every video you download or stream is actually compressed quite a lot, the bitrate just determines how much compression is applied. Higher bitrate means the file is bigger and less compression is done, while low bitrate means the video has a lot less bits to store all that data and so has to do more compression.
I played with my friend over Discord and somehow we got matched with each other the first time, so we didn't get to play with strangers or anything. Still was fun though.
These aren't browser games, but could still be fun.
I used to play Battle for Wesnoth a lot as a kid, both with my dad and by myself, and as it's turn-based it should run fine on a raspberry pi.
OpenTTD could be fun, although it may be a little complicated depending on how old they are. It's not very difficult in terms of challenge though, it's more of a sandbox once you get past a certain point. There's also sandbox options to give yourself lots of money if you didn't want to worry about money and just build cool trains and stuff.
I used to play a lot of Supreme Commander with my dad as well, so maybe something similar like Beyond All Reason or ZeroK could work if they take an interest to that kind of game. I haven't tried them though.
There's lots of FOSS music players, but none of them have a volume slider / preamp. The Android volume slider is always either too loud or quiet so I have to make fine adjustments using the preamp in JetAudio. If someone could add that to an existing music player that'd be cool.
