A game where ads are the main dish, but there's a hidden element

The hidden part goes up to level 80 and takes less than 3 hours to clear. But I swear, I watched over 150 ads in about 3 hours, no joke ㅋㅋㅋㅋㅋㅋㅋㅋㅋ If you don't watch ads, you absolutely cannot clear it within 3 hours. There are 3 ways to level up. The one on the right, increasing the number of cars or forklifts, caps at level 50. Instead of watching ads one by one, I recommend watching the level-up ads + helicopter ads and using the money earned to level up. There's also an event going on, so I recommend it ㄱ Ads are extremely frequent in this company's games, so give up hope and start...
