As far as we know these are currently the same series. It's a little confusing to even distinguish the two. They even seem to overlap one another. So they have been combined.

Why is samsara room included? Although it wasn't made by the same developers, many themes and elements from this game are used in the rusty lake series. It's not officially part of the series, but we included it anyway.

Samsara Room was probably made by at least one of the same developers, under a different name. If you look at the Rusty Lake website's "about" page (rustylake.com/about), you can see that the two co-founders and central members of the team are Robin and Maarten (who have withheld their last names). Samsara Room was made by a "Studio Maarten," so at least Maarten, and possibly even Robin, was involved in creating it.
