Just to add my opinion (and I pry this message was not deleted) is very diferent to complain about the time between releases, which is an opinion and a fact that all of us would prefer a weekly release with 4 hours of gameplay (obviusly is a desire that we will not get in any game) and a complain about how lazy a developer is and how he milks the Patreons.
You can explain and show your desire to have more content without saying anything bad about the game or the developer.
Aaaand like LarryK said (I think) you can also try other games in the meantime.
Aaaaaaaand if you really like the game and you want to show your gratitude you can do a donation (buy me a coffe works for me). This is not to speed up the work of the dev, just to show you like his work IMO.
