Fancade! It's a huge collection of user made arcade games. Most are trash but there are some hidden gems. It works offline, but it occasionally shows ads when playing online. You can remove these ads with money or by using an ad blocker.
Some other mobile games I recommend are Mindustry, PvZ and Luanti.
Do you want to have multiple color schemes that you can quickly switch between? If you have already built the configuration with a color scheme, the second time you build it should take much shorter. Changing between a fixed set of color schemes is also a proposed feature for Stylix: https://github.com/nix-community/stylix/issues/447
Similar tools you can check out are Tinted Theming, Pywal16 and Catppuccin.
I haven't noticed a difference between server and client side decorations when using GTK apps, but it's nice to have uniform server side decorations for apps that are not GTK
What I meant is that in order to share these games, other people would also need such a device or at least an SD card reader, which most people don't. It's not because of you.
I actually use NixOS, but my configuration also accumulates packages I will no longer use. Even worse, these packages will be reinstalled wherever I use that config!
