Well, I'm curious then. What do *you* think a good schedule would be then? Krill appears to be solo on the project, has work and life outside of this game. And those 2 updates in a year and a half are, when you look at it from just the player's perspective, HUGE. Massive changes in the UI, reworking the entire spell puzzle system, not to mention the animations and options for dress up. Including a whole back end for passive stat gain that has been promised to be more involved and used in future updates, meaning pre-emptive bug fixes. Not to mention being active and showcasing progress on the crowdfunding sites as well as here. And it's literally been 5 months since the last update, and they've repeatedly told us what they're working on.
If you think it's a scam, then just quit wasting your time and ignore the thread! If you think excuses like, oh, mental health, physical disabilities, family, jobs, and the like are unacceptable, then put your money where your mouth is and make a game yourself. And while those specific examples aren't in this thread, they are common in other threads where people like you think anything over two weeks is an unacceptable delay in the next version of a game you aren't even paying for.
