Jed's gallery of buttons is a find-the-button style map. There are 20 buttons hidden in the room. A few of them are straightforward, but most are very difficult. If you find all 20, tell me what time you got! :)

1.19.3, adventure mode, peaceful. Feel free to do everything within your vanilla minecraft power to find them. F5 is allowed but frowned upon.

There is no redstone, hoppers, or anything else unintuitive to make the buttons unfairly difficult to find.

v1.1 - Fixed one button that wasn't working and removed the easiest one.
v1.2 - Moved one button slightly and fixed one issue with another
v1.3 - Made one button easier to click
