it's looking great, and the pixel art is fantastic.
The elevator took awhile, idk what you have planned for that area of the game, but the elevator takes a long time to go all the way down. maybe to speed it up the player can select the floor from a menu that pops up when you press z on the elevator buttons. After selecting the floor, the screen fades black and then fades back in and the player is at the floor they selected.
hope that makes sense, wanted to leave some constructive feedback. love your pixel art
