Quick note, re-read the last sentence of my reply.
Not all of us have money to spare.
Meaning that if this current plan stays, one update will always be out of reach. This is without mentioning potential unforeseen delays in the future. Another thing is that while some do have money to spare, they might not approve of subscription services for one reason or another.
Again, I apologize for the impatience, and while my wording might seem hasty and/or rude, I just want to give some advice. Maybe an occasional devlog to let us know what's going on if something happens or otherwise doesn't go according to plan.
