Due to this version being based on Electron, it has a lot of security flaws. You can look over the source code(Github) if you'd like to veto those security flaws yourself. Alternatively you can use the SDL2 version: https://git.sr.ht/~rabbits/hiversaires
We're still busy porting our projects to Uxn. Hiversaires and Oquonie are on that list. We're a small two-person team, it takes a while to get things done sometimes.
