This is adorable and brings me back to when computers were personal and fun, even outside of games! I'd be really happy to see more quality personalizations like this popping up. 

As a Linux user, it's a real shame seeing "Only works on Windows!", but I don't lose hope. I imagine there's gotta be a clever way to package them for us penguin-system users, too! Will have to look into how this would be done. :D

The art style is so cute and yet isn't so obnoxious as to fatigue you from seeing it every day. I'd go NUTS for one featuring a chameleon for my OpenSUSE Tumbleweed system hahaha.

Keep up the excellent work!   Looking forward to seeing more of your creations. <3
