Here I will give you a game idea
At the (supposabaly) end you could make a crawling dead body going towards the character and if the character touches it the scene restarts which makes the character have to jump off the cliff and when the character does the title scene and after that you could make levels that gets creepy and creepier the higher they go untill the end is like.... Let me give you some choices
•The crow wakes up from a coma
•a black screen with a heart beat rate going down Implying the character died
•the crow driving to insanity
•the crow sitting in a room with its eyes popping out it's eye sockets
•a animation of a fleshy animal eating the crow
And at the end of that you could roll the credits and then you could make a crow picture at the end
I think the name should be..... Let me give you some choices
•The last day
•Midnight
•Fleshy crows
•Dimlit
(You don't need to do do any of this AT ALL its just an idea)
