Escape Game: Escape from the Cave

Pop-up ads have hints and answers, appearing after moving apps, etc. This author's games are really difficult. I didn't understand even with the hints, so I looked at two answers. I also saw a few that only had hints... I want to be able to solve these kinds of puzzles smoothly. Sometimes I see the hint and think 'Ah!' But there are times when I really don't get it, look at the answer, and think 'That's where it was?!' Also, the direction of progress is a bit unclear. It can't be helped since it's a cave, but... I almost gave up due to the cave and the difficult puzzles. For Blackcat's works, this author's games are difficult for my brain. There are no arrows or anything, so I get lost wondering where I can go, and 'Where am I?' I felt like giving up, but I told myself 'I'm in the middle of a challenge,' and pushed myself. I looked at the hints, looked at the answers, and thought 'Aaaah!' and cleared it. I want to be able to play this author's games smoothly someday.
