I was reading over the changelist and it seems so small. Is this literally all we get after waiting like 4 months? I wish I could just give $60, the price of a brand new AAA game, and just have access to all future TQ updates. I hate this "games as a service" thing that the dev is doing where you have to have a subscription to receive new content at any acceptable rate.
Patreon is not for subscription, Patreon is meant for "I like this person and I want them to keep doing their thing, so I will give them money, so that they can keep doing their thing".
You are supposed to remove your pledge at any time you don't feel like you're getting your money's worth. But the main thing about all of these patreons is the direct contact with the creator - you are their patron, anyway. You can ask for specific things and give direction to development. Like was done in this game! Diaper Quest is essentially the will of the patrons manifested.
But keep in mind that this game was designed in something that isn't meant for games like this (Inform7), plus there were big mistakes early on in development that will just make the game harder and harder to maintain, develop, and even play. Inform7 is really easy when making simple games, but there are pitfalls when developing bigger games which will cause exponential lag - for instance, if the way alternative names for things was done wasn't the right way (and I imagine it wasn't, because the "right way" is very restrictive), this results in Inform7 running any code like that for every single object in the game, which would mean that any time you add a new object, you just make everything in the game lag due to the alternate name code being ran for them too, and any time you add a new alternate name, it will run for every single object in the game.
There are (limited) ways of preventing these issues, but it is far too late now. I imagine Aika isn't doing much not because of laziness or anything, but just because the game has gotten to such a massive size that merely compiling it might be taking half an hour - imagine doing that to test every feature. For a text game.
Progress should be sped up if the game is ever recoded in some other engine, which I believe was the goal at some point (were they talking about Java? idk). imo a custom-built in HTML5 can be intentionally made as close as possible to I7 such that it'd be quick to port things over with near 1:1 code, with next to zero time wasted compiling, and maintaining support to all platforms people might currently be playing at, maybe even adding a few more to the list since HTML5 runs on everything.
Anyway, if you're not happy with the artist you're providing patronage, you can just stop. You are
not paying for the game, that's not the point of Patreon. You are supporting an artist you enjoy the work of, and you're supposed to stop as soon as that is no longer the case.
