Actually, I haven't loaded it yet. Been busy getting ready for the weeks runs.
I listened to you in the recordings. Sounds great. Your English is fine. Your words... Some of them I only know because I know mapping however. The accent makes some of them sound... Not clear.
Anyway, the main drawbacks of this method are that it doesn't really look like a volume, and that its not getting blinding when you look straight into the light.
I know what you said, what I heard was a totally different thing.
As for the tutorial, I like the idea. If we had visual tutorials when I first learned, I might not have acquired as many bad habits. I would suggest that if you could fix the tutorial to be interactive, as with the "Lost Coast" demo, you'd win many kudos.
