Sorry, I really should be used to just posting the error log.
Anyways.

After a few attempts to access the first area with the relay dish, I backtracked and looked around to see if I had missed anything. Once I obtained the Rokvoxx core and tried to use it to change the music, the game stopped running and exited immediately.
Other than that, I enjoyed playing this demo. I look forward to news on the full release :)
