Let's defeat the boss too!

I got hooked on how fun the speedy growth of the kitties is, and I played a lot yesterday, so I was able to clear Stage 20. I'm running low on blue diamonds💎, so today I'm going to challenge the boss-defeating icon. Watching ads gives you a lot of diamonds, huh? With the diamonds I collected, I strengthened my weapons and bought pets, and it's become more lively and flashy. I don't really know what's so fun about it myself, but I'll enjoy it as long as the hidden quests continue💪 I usually hate watching ads, but I thought the ads in this game weren't that bothersome, and then I realized it's because most of them were for other games, and there weren't any annoying ads about losing weight or whitening teeth that I didn't want to see. I think the ads people see differ, but I haven't felt much discomfort so far. I think that's also one of the elements that makes this game enjoyable.
