It's too difficult, so I'm reluctant to play.

Watching ads appropriately does act as a lubricant for game progression.

Whoa, you can't clear it without watching ads? That's seriously unfair! ㅠㅠ I was worried since you said the last game you played was boring, but this time the difficulty is the problem. It's the weekend, I wish I could just relax and play games, it's upsetting.

Most games start easy and then make it impossible to progress without watching ads..

I agree..
