Nice work on the art, as mentioned by others already a bit more direction would be super helpful.
Feedback; A bunch of the props are missing colliders so you can walk through them. If you want to fix the white lines issue that persists in your side walk art you can through the art into an sprite atlas. You can complete the top down effect by splitting your art assets in half so the top part can be on a layer in front of the player while the bottom is behind the player. Combining that with a collider thats half way will give you a nice effect for walking around objects like light posts and trees.
and again congrats on completing your second game jam
