By the same logic, Rebel Duet is also a "free game" and yet it has been given an absurd amount of development time. Looking over at some of the posts, it seems as though you have a devout following for Casual Desire, some of which are paid supporters whether it be via Patreon or otherwise. It feels as though you're burned out and have lost interest in developing Casual Desire. CrubMuncher and Trf95 have excellent points and your lack of progress is telling.
As a soon to be former patreon supporter - perhaps it might have been better to finish one project before starting another. Alternatively, you could have easily given the project over to someone else, say, the modder Homatoz or someone else who shows more passion (or lack thereof) for the game than you do
