You do know, don't you, that you haven't been paying anything for your pledge? RDG doesn't charge his patrons monthly. He charges per update released for the game. So, until version 0.6 is released, no one is being charged. With that being the case, I can't see any reason for him to suspend anything.
I, for example, have been a patron since a couple of weeks after version 0.5.2 was released, since that's when I discovered the game. Since that time, there have been no updates released, so I have yet to be charged even once for my pledge.
