I think the dev should just proceed the way he is doing now. I find the game to be one of the best on the site, specifically due to the multiple paths and possibilities.
I know it's going slow, that's why I forget about it until a new update comes out (Or sometimes I just skip an update)
Sometimes, the best games are worth waiting for. There are a couple of games on here with various amount of content each update, that gets released more then 3 months apart. They are probably the best games on this site.
