Jamming Godot

This is my first game game made with Godot. It actually looks like a game.

NOTE!!

Every tilemap, background and the sounds are not made by me. I just borrowed them from the internet. I only made the character, slime, the coin, heart, score, i made the animations.

I would like some opinions and some advices. In the future i want to make a open world sandbox 2d game.
