Yes - https://github.com/tobspr-games/shapez.io Though it’s also on Steam for a small price to support the developers
More recently, I’m a fan of shapez (shapez.io) for my recommended daily allowance of factory building gaming.
Going back further, I have a soft spot for Ri-li, a nice little game about toy trains with very charming music! It was this which set me on an adventure with the mod tracking scene. A surprising amount of open source games use them, it feels like open source music!
Reminded me also of Alex the Allegator 4, a very original 2D platformer
Do you mean the Ur-Quan Masters? It recently released on Steam!
I find it really depends on the brand. I have no idea what the differences really are (or even how it’s made in the first place) but in my experience around half are as you describe and half are delicious
