Yeah the controls are more of a fps style with jump being space, but in the future i want to add key bindings so it can be customized. The scale idea was initially going from planet to space and vise versa. we also were attempting to add more scale with political intrigue between systems but unfortunately the game jam was only one month and not 1 year XD.
The parts that were procedurally generated were the planet designs in space as well as size and location. Once you land on a planet each world is proceduarally generated as well. On world itself i did by custom making chunks and the chunks are generated based on an walking algorithm i wrote. if you are interested in the source code since you are a fellow godot dev the on world generation is done in the "planet_generation.gd" located in the test_remove_before_export folder (i forgot to move it to a permanent place)and space generation is done in "stats.gd" located in the singleton folder.
Also thank you so much for playing and your feedback! I really appreciate it since Wolf (the other dev) and I want to keep working on it and improving it XD i know everyone says that but based on the positive feedback everyone has given it really motivates me to make it a full game. So thank you again!!
