What should I do?

It's my second day playing. At first, missions were shown, but they disappeared partway through 😢 Maybe they want me to play freely, but I don't really know what to do or how to level up 😣 While fiddling around, I somehow managed to reach level 5 of a hidden quest 🎉 There were also several hidden quests that involved watching ads, and I cleared those too. The next hidden quest is to reach level 10. I'm still in the dark, but I'll give it my best shot 💪
