Hey, forgot to post an update yesterday. Yesterday, I spent a bit of time investigating how to make 2D sprites. I found some free kitty sprites and then spent the rest of the stream trying to figure out how to properly import them into Godot. I also found LibreSprite for editing sprites. At the end of the stream, I had an animated sprite of a kitty walking.
Today, I focused on building the room for the kitty to play in. I spent a lot of time watching tutorials on tilesets, tilemaps and learning how to do them in Godot. I had limited success, I found that sometimes when tiles overlapped, they wouldn’t overlap in the correct “y” order that I wanted. I was unable to figure out how to “fix” that. Not sure if that is a bug, or just subtlety of the interface that I don’t understand. It is tricky using 4.x because a lot of the tutorials are for 3.x. 3.x is significantly different from 4.x.
“y” order issue can be demonstrated with this screenshot

The red box shows what the picture tile looks like after trying to place it on the wall. It seems like it is behidn the left tile and on top of the right tile. There doesn’t seem to be an obvious way to move it up the “y” order. The only way I was able to get stuff working was by having multiple layers. Maybe that is the way I’m supposed to do it?
Here is a quick screen recording of where we ended the 4th stream.
