First of all, hello to new patreons! I'm so grateful, I never expected this response.
Please don't hesitate to get in contact if you have any questions, or if you're having trouble with the early access. If you like Discord, we have a community for discussion of the tool and sharing of maps. You can contact me there, message me here or on Twitter @probabletrain, or email me (probabletrain@gmail.com).
On to the latest changes! Brushes now have preview outlines so you can see their size before drawing. I've also made some big behind-the-scenes changes to reduce lag when using brushes (especially the path brush). It's live now on the itch.io page.
