Is there any possibility of you making the source available?
Viewing post in Cactus vs. Dinosaurs (Godot Wild Jam #6) jam comments
Sure, here it is: https://github.com/joaquin-montesdeoca/godot-wild-jam-6
The only thing is that the commits and some comments are in spanish, but the rest of the variable and function names are in english.
It should work in Godot 3.1.
Edit: it should be noted that the repository was just private, so even the README.md is the default right now. :P
