Well, it would be a lie to say I'm surprised by this. I figured this game would never be finished when the logs started to pile up basically saying the same thing "we're trying our best but [bad thing] happened". It's good to see that you are honest towards people who gave their money to this game. Truly a shame that happened, the demo was fantastic. I hope to hear from you again if you ever decide to start another, less ambitious project.
Thank you for the notice and for trying your best.
