Wasteland Trade: 방치형 좀비

I've played a similar game before, and back then there was a time gap so I was able to complete everything. This one only has 7 days, so I'll wrap it up around here. Since there's a similar game, I couldn't focus on this one. If you play up to 3-6, you'll probably finish all the hidden quests.

When I launch the game, the arrow appears in the bottom left corner like in the first picture, and I can't interact with anything else. When I click that arrow, another arrow appears in the middle like in the second picture, pointing to an empty space. Clicking it does nothing, and I can't click anywhere else. Does anyone know how to fix this?

No matter how many times I turn it off and on, it keeps happening like this. Pressing the arrow part does nothing. Has anyone figured out how to fix this? ㅠ

It's so hard to do the hidden stuff ㅠㅠ It's okay at the beginning, but I don't have enough time Watching ads is a pain ㅠㅠ Money just doesn't accumulate.

This is impossible

It's an idle game, but it's surprisingly fun~ Seems like a decent casual game to play~ Happpy weekend~^-^

The reward for watching 40 ads is really great haha Have a great day today~~~❤

Help me

Watch ads and get rewards~~❤❤

I thought it was an idle game so I'd just leave it be~~ but pressing the buttons is surprisingly fun and I lose track of time playing it~~^^
