Games [WIP] Rooftop Postgirl - Indie Platformer Adventure Game

Hi everyone! Well, I've been working on a game project for years. I still have only the Demo, but I would like some feedback. It's a 2D pixel-art game about delivering letters jumping from one building to another. Kind of like a mix between Paperboy and the old Mario games. Also, I'd like to say that the story is... quite interesting... I guess...
It's singleplayer and I think it is a pretty funny game. If you'd like to check it out, it's called "Rooftop Postgirl".
Here is the itch.io page.

Here is the game trailer:

Finally, I'd like to say that this project used to have another name.
It was called "I Don't Know Which Name I Should Give This Game"...
It's much better now, isn't it?
