Then Impy support drops, she moves on. She was already intending it to be a short 3 month game like her old ones, we all held a vote and over 120 voted for her to make it a year long endeavour. But why do that when people can take the premium version? Nobody would need to support her so she could just stop making it. Then you'd have no game to be behind. But then you aren't really a month behind, you get updates same as the premium. V5 with new features becomes public around the 10th then a month later you get V6, then a month alter V7 and so on...
Everyone eventually gets the same version, all that is different is if you are willing to pay you get to play early. I've found most people on F95 are willing to honour that arrangement if it's just a 1 month gap but eventually everyone gets the version.
