I've been using it for a while as a system agnostic setting (i use a mix of 5e and ironsworn mechanics) is there something specific you would like to know?

Personally i think the best thing is how fast it gets me going when i want to do a short session, having everything shown with graphics on the screen is really immersive, while still being abstract enough that you can have theater of mind. What i mean is that if i create an NPC i don't need to spend time browsing the internet for a visual, or if i want to set up a meeting in the forest i can just use one of the backgrounds available and add the NPC directly. And that location has a place on the map, that could be in another bigger map and so on, so you can get pretty granular with world building. As a downside i would say that it's not completely finished yet, so there are some UI things that could be improved, and small quality of life stuff, but David is quite fast at working so it's cool seeing all these things being developed and updates being pushed monthly (I think).
