Legacy-home of tricks-hint needed

[rakanishu]

I'm neerly at the end of house of tricks where a sign says -Detour wall one and three - and I'm blocked by a grey wall ,there's no secret buttons anywhere and I'm sure this path leads to the key needed to access the sphere-edited to say sorry that I haven't post in the thread -Legacy - Help With Quests - to anyone that bothers

[rakanishu]

sorry for the thread finally arrived to the solution in the thread: Legacy - Help With Quests
quote "try to remove that detour's other wall with a secret button from the north, beside a shelf. (The blue orb room contains only one removeable wall from the two.)"
bah
Anyway thanks for that great game
