Sorry :( The only thing I can recommend for this instead is watching the YouTube tutorials (they're linked on this page) and also joining my discord server and asking other people what they think or how their experience has been.
Eventually I'm gonna be uploading even more tutorials, and also probably even some devlogs so that you can get further insight, but for now what I mentioned above is all I can offer you.
When the tool goes on Steam we might have a demo, but that's a long ways off.
