I hope to aim for once-a-month updates again if all I need to worry about is 1 predator, but techniques and quality has changed significantly as development goes on, so it is hard to know if the 1 month timeframe is still feasible.
I may have been vague when saying 60% complete, that was in reference to only the next update involving Turtle and Mermaid. Total game I would guess is at about the halfway point, but that too is hard to quantify.
