Hey hey!
If your looking for a way to add logic to your top down character, to make it move and animated in the style of SNES games like Legend of Zelda: A Link to the Past, then i have just what you need!
Instead of giving you a long and boring explanation on how things work, you can simply download all the events that your gonna need!
Heres how:
- Go to https://retrogamelogic.itch.io/gdevelop-top-down-events and download the .Zip file
- Unzip the file and Open it in GDevelop
Now follow the video guide bellow on how to easily import these events onto your top down game project and make them work with very little effort!! 
If you found this helpful in any way, please consider supporting what i do by buying me a cup of coffee
If you need any additional help, let me know and ill try to explain things better, or make any sort of adjustments if needed
