Well, we should be impressed with 25MB for a decent game editor since the other players like Unity and Unreal Engine are probably around 25GB. It's also a fraction of Slack or Chrome or even the Rust compiler I believe.
The Chromium package on Arch Linux is around 68MB. The Electron runtime is a surprisingly reasonable size. Interestingly, the Go package is over 110MB. Rust is larger.
The Chromium package on Arch Linux is actually just a bit under 200MB when installed. Are you looking at the download size?
Yep, you're right, I'm looking at the compressed archive for both. Go must be huge then if the compressed package is 100MB.
I didn't check, but if the package consists mainly of binary, optimized executables, the compression may be very limited...
