Godot intro

you can change the type of game your making from 2d to 3d to coding(script) at the top of the screen

To the left, This is where your nodes are, these are the building blocks of the game your making.

inspector tab, this is where you can change the properties of the nodes

I dragged the piskel file in to Godot, in the file system, then Tileset to make collision layers on tiles that will be in the foreground and interacted with by the player. To separate the foreground and background I used layers, it is important that the background comes before the foreground, so you can see the tiles Infront.

This is the foreground view of my game so far, I need to add more detail to the background because currently it is a mix of two tiles, and also spread the door out between a few tiles so it is the same scale as the rest of the scene.
