I loved the intractable title screen. I'm playing in the browser on a chromebook and the web build is crashing like you said. Hopefully someone streams themselves playing if you don't add screenshots later.
Thank you TheImmuneCkay. The best way to play the demo is to download it. Three versions are available windows, linux and macOS. File is really small (about 165Mo).
I could have added a video showing a succesfull run but I don't want to spoil the level exploration.
