The Theme for the gamejam was 'Down to earth' which kicked off the thought of being tiny in a big world. We naturally looked at Alice and Wonderland for inspiration and started to model big mushrooms, leaves and the vine forest.
The plant in the astronaut helmet came about when thinking of a reason why you are on this journey, it came from story generation; You arrive in orbit, you go 'Down to Earth' and you have an objective, a plant in an astronaut suit made a lot of sense (In reflection, that sounds weird).
Filling in between the lines was just letting our creativity take over while we developed (Such as the interior/ruins area and the final sequence).
