So if you still haven't figured out how to do Anthony's route basically after surviving a dinner with Isaac you must go to the garden and once theirs a rampage going on and nate went ahead and put you in the wardrobe and then choose the option to seize the opportunity to leave which gives you 1+ power since you can only get this option once you have already went to the garden and then you meet up with Anthony in the garden!! And honestly I'm glad that more people have love this game I've played it a few month's ago and I'm still hooked, you should also try out the other games!! Although the other games has more mini games which depends on you if you like said games but still they're amazing!!
Hi there, As Keyria stated you have to explore the garden at the start of chapter 3 before the castle attack and take a walk. Doing so, you will discover some vines along the wall that are strong enough for climbing and will make a mental note to visit this place again at a less conspicious time. This will unlock the option to escape from the wardrobe and return to the garden when everyone is distracted by the carrier attack. Feel free to ask any more questions if you still run into difficulty. Good luck!
