I haven't been able to reproduce that unfortunately. Which browser and OS is it?
In the meantime, you can try the binary builds.
It's just when I try to launch the binary through itch.io app. Windows 10. I see this message right after the load bar. I'll try to reinstall it. UPDATE: Reintallation helped!
Oh, thanks for the feedback. I didn't think to try running through the itch.io app.
