To put it frankly, the prices associated with the June event are absolutely ludicrous. A single base applicator costs 400KB, but there's 5 in the shops. Let's say you're incredibly productive and you manage 100KB a day (an unrealistic goal for most players), you'll only manage 3,000KB in the month. If you spend that all on bases, that's 7 bases. And that's assuming you buy no decor, and you always manage exactly 100 every single day.

To actually show you how impossible this is, I'm going to do some math real quick. Scary, I know. Let's say that someone doesn't sleep, at all, the entire month of June. They are on nothing but Lioden the entire time, but don't use Roasted Lambs, and they use 11 Energy Bars a day (the 9 full ones you get per day + the daily bonus + hyperactive + enclave boost). We're also going to assume someone gets a Snake Encounter for every step they take in explore, and they win every single one, and they use every single KB they get on bases.
They earn 220KB a day, 6160 for the month. That's a total of 15 base apps, for no sleeping, just continuously playing Lioden, under ideal conditions in explore. "But Jester, what about the quests?" Daily quests boosts them up from 15 base apps to 16, as you only get 10KB per day from them, and you can only do 28 of them for the month. This means that, as of 2024, when the new base apps are added to the June shop, you cannot get 1 of each base by swapping between Gods. You will not be able to by earning 220KB a day.

Now, to do the math with sleeping, we're going to take 8 hours away from that, for a total of 16 hours a day. Adding in what we did earlier, that's about 7.5 energy bars a day. Under the same ideal conditions, and doing nothing but Lioden when you're awake, that's 4,350KB, or 10 apps. Even adding in the extra 280KB you get from daily quests, that’s 11 base apps for the entire month. Doing nothing but Lioden and sleeping, and only spending your KB on base applicators. With this, you can't even get one of each base app that's currently in the shop.

These numbers are also only for one account, but also in ideal conditions where you get an encounter every step, win every battle, and spend no other energy on breeding/stud requests. For less than ideal conditions, these numbers would drop dramatically. AKA, these numbers are physically impossible. I've found some of the highest earners in June to only be averaging about 100KB a day, if that. That's only 2800KB a day, or just 7 base applicators for the entire month. For context, I bought seven Spicy Ice apps from December, and that's not even all I got.

That means for each base app in the shop, if you do nothing but sleeping and playing Lioden, no taking breaks, no stopping to eat, no anything, you can only get 2 the entire month. To take a month with comparable base applicator values, like February with the Cherry Blossom base, you can get more than DOUBLE that amount and still have enough event currency left over to do some decor shopping.

It's just ridiculous that bases cost this much with the amount of them that are now tied to the month, and are required for breeding rare and pretty popular combos as well.

Another potential option is to drastically increase the amount of KB provided by each snake, up to around 10KB a battle, like the October Night Creatures provide. That would make grinding June actually worth it, and not just a slog sandwiched between two battle heavy months that leads to extreme burnout. Though, to be honest, I think both should be implemented together, especially now that they have two shops that use KB, and plan to increase both shops loads every year.

POST JUNE DEV UPDATE:
No real changes in the amount of KB that I've noticed. All the new encounters seem to be quest locked and with no information about them on the wiki, I can't really see if their numbers are any different. From what I've noticed with the quests I've gotten, it doesn't appear to be so. In fact, both the find a cultist encounter and the find a boat encounter don't even reward KB, just a +50EXP and a quest completion.
