Come on guys. we are getting the game for free, and all the dev asks for is voluntary donations to those who enjoy the game. And Ecchi Sense is persistently high quality and fun, which is more than I can say about 80% of the games on here.
As long as the dev is communicating with his fans, I don't see the issue, however long it takes. As anyone that has been around here awhile, there are a lot of great games on a 6 month or even longer release cycle. Is it helpful to browbeat the devs, complaining, until they decide to abandon the game because they are tired of all the trash talking?
True, a lot of us were spoiled with Ecchi Sensei's quick updates in the past, but maybe it is moving toward the typical for games here, which is a 3-6 month release schedule. I can point to lots of games that take even longer.
I am sure a lot of us would be happy to see the mechanics fixed, and some new content, but things happen. I sincerely doubt that any of the ES developers are getting rich of this game. If they are making much more than minimum wage with all the labor, I would be surprised. Besides, that is up to the patrons, like Ickerax said. If they are happy to continue donating, than good for them.
My suggestion is play something else while you are waiting. Once in a Lifetime is about to come out with a big update, and it has lots of content. Alexandria just game out with an update last week, and that game is always great, and quite long. AOA Academy is amazing if you haven't tried it, and it was also just updated.
