Thanks! I used Krita to create all the textures and sprites. All the textures are vector splines with a fill / gradient since it's difficult for me freehand. Godot's engine takes care of most of the color shifting / layering, so there's a great amount of reuse with the backgrounds and sprites. For example, the Seedlings and Sproutlings are actually just white/gray sprites, and I have Godot turn them green or wither them yellow. The Card backgrounds are reused for the dialogs and buttons, by adjusting how much of the texture is used and the settings of the Node.
This was my first time using GDScript outside tutorials, as I wanted this one to run on web. It was just as flexible as using C# to swap out the sprites dynamically and creating animations on the fly, and the coding with it was pretty straight forward once you get used to it.
Are you participating in the Jam? I feel like the easiest way to learn game dev is to have a driving force to it, and Jams give a deadline, topic, and critical feedback. Then, you can use that feedback to hone your skills and thought patterns towards making your dream game later. You also don't have to do it by yourself, I believe there's a pretty healthy amount of people on the Jam's discord server looking to team up.
