Finally, after several reports I decided to not make mandatory clown's puzzle. During its development I also had doubts about adding an arcade minigame inside an adventure game. This puzzle should have never been mandatory to continue the story, so now you can directly get what he is protecting. However, you can play with him as before in order to unlock achievements.
Also, a couple of translations in english were missing in the island (thanks Twitch community)
Thanks for playing!
