Looks like it's around 2.5' and the Webb image is rotated about 15 degrees clockwise from this one. The four blobs to the left form a quadrilateral that seems to match the four bright galaxies in the Webb image. It seems like the star has moved maybe 10" downward between the two, and used to be just below that round galaxy to the left of the top spike.
Firefox (and all browsers on iOS) is just a wrapper around the Safari engine, because of Apple rules. On Android and desktop (including MacOS) it's fully custom.
Full game doesn't crash, doesn't give you the browser scroll function on middle click (the shortcut to pick a color of an existing building), ability to export as STL, no full game links, ability to create oversized screenshots, some settings. The full game isn't deterministically equal to the browser one (roofs slope in different directions sometimes, decorations in different places). It should also run slightly better, although both are pretty lightweight.
Notably, the export strings are the same.
Basically: you're not missing anything from the core experience, but the browser version is slightly inferior. And buying the full version helps Oskar make more neat stuff in the future.
Wat? The easiest way to build up a large collection of files, especially one that is only worth it to back up if you can do so inexpensively, is downloading movies. I would guess this describes most people who store lots of data.
Also, the lesser number of people storing large amounts of original data (eg videographers) probably create enough community goodwill to make up for the cost.
I'd guess at least half of the colors are extremely unlikely. Anything near the edge of the RGB cube would require some very uninspired artwork to show up in the set.
