If you're looking for a similar type of game, I played GRIS recently which reminded me quite a bit of this.

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.

Croc, although it's command-line only.

Syncthing is also great but may not be what you're looking for.

I love this meme format

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.

Not a mood tracking app, but I've been using Loop Habit Tracker for like the past two years and quite like it.

You can also run the game at 1080p and use FSR to upscale it to native resolution, that's what I often do on my 4k monitor.

I believe Syncthing isn't on iOS.

On System Settings’ Night Light page, the time input fields for manual time mode are no longer a nightmare, because they’ve been replaced with a set of spinboxes (Natalie Clarius, Plasma 6.1)

Oh thank goodness, that page has always felt a bit weird.

On KDE Plasma there's an effect to zoom in the whole screen on your cursor (it may be windows-plus and windows-minus or you may need to set it yourself). I believe Windows has something similar as well as an accessibility feature. I should think that would work when screensharing.
