Acknowledge Event Mission

Cleared level 20 in just under an hour ✨ There are also time quests and hidden quests, so I think I'll continue for a bit longer. It's a little hard to understand without a tutorial, but it's easy to progress by connecting vertically, horizontally, and diagonally. Even with ads, they're only about 5 seconds, so it's tolerable. If you have time, give it a try!
