+Welcome to queen2!
+-----
+We just learned about creating a GUI for applications, so we had
+to try it. It's very basic, but it works! WOW! A new level of user
+experience in contrast to these old style command line programs.
+Sometimes, this event-stuff is a bit tricky because you don't
+see directly which code is executed if you interact with the GUI..
+
+Can you uncover the secret message we put into this program?
+
+The flag is also the password for queen3.
+
+
+Hints
+-----
+A debugger could be of great help after you identified interesting code regions.
+You get the flag by passing your findings as parameter (in decimal) to the `get_token`-command on this VM.

+
+so the number we are trying to get is: 0x5620 ^ 0x1033 == 0x4613
+
+values of buttons were for me:
+
+0010    0040    0800    0020
+
+0100    0400    0080    2000

+0200    0004    1000    0008
+
+0002    4000    8000    0001
+
+which results in the pattern:
+
+x o o o
+o x o o
+x o o o
+x x o x
+
+x=pressed
+
+now read this pattern left to right, top to bottom as 16bit variable, msb first
+
+in my case: 0x848d == 33933
