Before crying in fear, angst, and rage because a node to draw that specific something does not exist… it would be good to know that it is possible to easily make any 2D node (be it Control or Node2D based) draw custom commands. To aid in this transition, it is worth mentioning that Godot uses similar APIs for 2D and 3D. You basically instantiate an array like normal, and then loop to create arrays inside that array to form your grid. y = -1 on any appropriate node2d near or at your project's root, and the universal transformation to y=upwards will be done for you automatically and without any performance cost (that matrix multiply was already happening, you've just switched a +1 in it to a -1).

Layer 2 is the pieces overlayed into the cells. Godot will simulate the Particles2D node emitting particles for a few seconds and set the rectangle to fit the surface the particles take. What I'm suggesting is not a left-hand coordinate system but a right-hand with Z-up and X-right in 3D, and switching the sign of Y in 2D. The project window appears blurry, unlike the editor. The goal of this tutorial is to teach a way for feeding input events to the Input with a position in the correct coordinate system. 2D top-down games don't really need physics like falling. Introduction to editor development A 2D vector using integer coordinates. Usually, the X axis points to the right, but the Y axis can point up (in the case of many game engines) or down (in the case of screen coordinates and in Godot). Godot is no different.
