Long enough for me
First, I like this serie. It looks professionnal, even if (I assume) you work alone or in a small group.So, keep up the good work as long as you enjoy it (and if you one day don't enjoy it anymore, think about a good end and make it before letting go...
And I think it was long enough, thinking about how much job it must be. Also, this is not paid material, so we don't have to expect 15 minutes per episode... I look at a serie like a film in progress.
Thanks.
