I'm really happy you liked it! Godot has a built-in graph system (GraphEdit and GraphNode nodes) but it there is some assembly required.
I used Unreal Engines Blueprints as the main source of inspiration, with Blenders Shader Editor as a second inspiration. The music and sounds are from Ovani, who make great audio assets. I tried to add sound effects where possible, such as connecting nodes, as I believe game feel / juice is very important, even in more mechanically-focused games.
I've had over-scoped ideas for projects utilizing a node-based system, but couldn't justify the time-cost. When I saw the game jams theme, I thought it was the perfect opportunity to learn how to make the system, and get feedback on whether or not people would want to play a game like this.
I like programming, but not everyone does, so I tried to gamify it, and I want to keep it accessible while allowing player freedom for more advanced players. Once the game jam ends and I clean up the code, I plan to add more content to the game, as I ran out of time during the jam. Thank you very much for the feedback!
