Hi! I have a few ideas that I have been fermenting. They don't necessarily fit together but rather than writing a ton of posts I though it best to put them all together.
Subscriber Incentive - I like the vanity/clothing and teleportation advantages currently in place, as they don't make subscribers some sort of exclusive club (ew!), but there are a few other opportunities that might be worth thinking about.
Bag upgrades - either a subscriber only Slightly Larger Bag, or if that sounds icky, perhaps an automatic upgrade of a slot or two to normal bags for subscribers? Inventory space is important, but not a game-breaking advantage imho. Giving subscribers storage advantages (even small advantages) would make subscribing more delicious. An issue would be managing lost storage space when subscriptions lapse.
Events - Let subscribers post special public party invites somewhere everyone can see them. I haven't been to an event yet due to either (a) not knowing it was on in the first place or (b) timezone issues. Events could show time and date in the players computer time, or perhaps you could even click a button to receive a countdown and/or updates on that event. Help all the Glitchens get together!
Let us make ALL the base cooking items!
Let us brew beer from wheat and honey! Let us fruit change olives and press them for oil, which we can combine with lemon and salt and pepper to make oily dressing! Let us brew hooch from fruit or milk fireflies for honey! I can't think of any base item that couldn't be manufactured somehow - adding these as higher skill options would keep the game chugging along nicely :D
Fish are a tough one though. I would prefer the idea of a whirlywind creating fish rain rather than 'fishing' (which seems to be added to every game). Maybe higher levels could call up whirlywinds to start a fish rain to harvest fish. Oats seem more like a crop kind of ingredient. Sesame oil comes from sesame seeds of course, which are a pretty valid spice option (I know I have some in my spice rack). Same things goes for coffee beans. Just don't ask me about the Crabato Juice!
Custom Houses
I love arranging furniture. I'd love to mix and match the veggie Groddle decor with the polar bear furniture, and use it to brighten up a minimalist Alakol mansion. Furniture could create a whole new arc to the game (use some planks and carrots to make a Carroty Footstool, for instance) with new skills and items, and something more fun to do in our homes. It would take a lot of work to develop something like that, but partying with purple in your new purple apartment could be a lot of fun.
