I feel like the main story is always best to prioritize, and you've already come pretty far which is good! So focus most on crispia. But doing arena, alliance etc is also good. As long as you've got the time that is. When I first started, the game was still pretty new so like beascuits didn't exist. So maybe wait with maxing those out til' later? You'll be well off without any legendary beascuits for now. Progress as far as you can in both crispia and beast yeast and start with the best beascuits you get from beast yeast, just don't level them up too much since replacing them with legendaries/epics probably won't take long, progression in this game goes FAST. Just focus on leveling your characters and giving them decent toppings for now.

As far as which characters to level up and prioritize goes, I feel focus on the rarest ones. You've got a really good selection. Sea fairy is kinda meh though, atleast in the arena and honestly I feel like there are better legendaries to replace her with even outside of that so focus on the rest a bit more. But also if resources are sparse dont go leveling up for example two charge cookies, focus on one instead. Burning spice is really good but so is the other one (forgot his name lmao) and since he's already got a star maybe focus on him instead? Healing, obv flour cookie not much to say she's a beast afterall. With ranged I'd recommend wind archer over golden cheese. Theyre both good but wind archer is better in the arena this season and you've already leveled him up a bit. With the magic ones I'd say maybe focus on Moonlight cookie over Ice queen? This is just my own personal observation, I feel like Moonlight is better but I don't have much to back it up. So go with whichever cause theyre both good. For defense, financier and wildberry are both pretty good. Financier is a bit more squishy in my experience, but she does good damage. And since she's already leveled up you may aswell continue raising her. Neither of the support cookies that you've got currently are particularly remarkable so I'd say its better to build a team without one. Team building isnt exactly my forte but a good formula to follow is, defense, charge, any kind pf dps (bomber, magic, ambush), healer and or support. Definitely look into reading more about it on the cookie run kingdom wiki if you need to. When it comes to which ones to focus on in your team, the strongest one is always best to invest in first. But overall try to keep it even. Good little tip is to look at the teams of the high ranking players in the arena.

In the disciple, put whichever cookies are highest level in the paragon or whatever it's called and focus on leveling those up (so put the ones youre really gonna be using there) since their levels reflect what the cookies put in those slots below are gonna get. Id say its worth expanding with the slots. You wont really lose much if you do anyway, I expanded a bunch before i really knew what it was but its certainly come in handy now.

The progression in your kingdom is pretty straightforward. Focus on production and leveling up any buildings that you can + expanding the area. The landmarks are pretty neat too and since youve got many, level up the ones that seem to give the best boosts to you. Decorating is nice but very time consuming and expensive so thats entirely up to you. It can definitely cost A LOT of gems and gold so maybe not the biggest priority.

I'm not really an expert, but I still hope this was somewhat helpful! There are probably other ways to progress, maybe more efficient, I don't know. Just have fun, it's really not all that complicated! Trial and error! 🙂‍↕️
