This escape game was rather tricky to figure out the clues, so when I eventually found everything, the ending challenged me to find a mysterious Happy Coin.
Without spoiling the secret, I will provide a hint:
Once you find the final key of the game, use the binoculars to reveal the final clue of the game!
If I can find it, so can you!
Recommended: Yes of course! 😁👍🏼
