Don't bother with Patreon unless you plan to spend at least $5 monthly... there is a $2 tier, however all it really gives you is access to the Discord, and you will still be fully two updates behind on the version of the game.
Essentially, this means that if this game takes a year or more to develop, you won't get any real benefits from the patreon unless you spend $60 for that year (assuming the project actually finishes within that time frame, which does not seem to be the norm, and does not track with the schedule so far) and only if the game finishes within that year (this equates to AAA game title cost). Recommend sticking out the free version, for obvious reasons, taking into consideration both the time between updates, and the size of the current product. I can't recommend any dev that only appreciates their higher paying supporters, and not ALL of their supporters.
