Fly to Heaven

Welcome to afterlife!  You probably already guessed yourself that you died... but don't be sad, you have a long, without exaggeration, road to Paradise ahead of you!  But there is one problem... the darkness that will always be behind you  , it will try to swallow you along the way, so if you are not fast enough no one will help you here.  On the way, try to avoid the clouds that will delay you, and in general it is better to hurry.  Well, good luck!
