Thank you very much!
We will fix the elevator issue in the next update – 1.1.2!
As for the last two things:
- one of them involves finding something you can do in the gardens, rather than a character asking you explicitly, so it's not as obvious, but you should be able to figure it out if you look around!
- the second one is actually on the.. other roof, rather. The roof-roof. We are going to fix the collection icon for this one in this next update too, because it's probably misleading, so thank you for pointing it out!
Hope this helps, and good luck!
