We're so sorry to hear that! We understand that it is really hard to attempt to skip through this demo (trust us, we've had our fair share of clicking through while troubleshooting). We're at least glad you liked what you managed to play through!
This is actually the older demo so the crash might be a remnant of this older version. That said, we wouldn't be surprised if it was still there in the newer one. Just how it goes sometimes...
Either way, thank you for playing and bringing these issues to our attention, we will look into all of them moving forward!
