Misc Computer Games - Resident Evil 3 - Mysterious Orgel Theme - Mysterious Piano Theme Chords & Tabs

Hey :) 
This is my first tab, and I am fairly certain this is correct. 
However, should this not be the case, I apologize and welcome corrections :) 
[ Tab from: https://www.guitartabs.cc/tabs/m/misc_computer_games/resident_evil_3_mysterious_orgel_theme_mysterious_piano_theme_tab.html ]
This is played in Resident Evil 3: Nemesis as part of a puzzle. 
I watched my brother play the game a great deal of years ago, and this one 
tune just stuck with me for some reason. 
So some time after I started to play the guitar, I wanted to find it and learn 
to play it, but I was unable to find it. So I tabbed it out.
Hope you enjoy it :)
