Wow, that's one comprehensive and detailed review. Thanks a lot.
I think we can mostly agree with your observations, even the one about music. We never had original music in one of our games, because none of us is able to create it. We selected and added the music for "Only in Yazoria" at very short notice, so we might have missed better options.
Actually we did the whole game at short notice. Two months of time were too much for us to handle...
