900GB? That doesn't sound remotely right, the entire unzipped folder is no more than 3GB. I have no idea how it would possibly ask for 900, I don't know if there's much I can do to help you there. As for the Steam question, I currently prefer leaving it on Itch as I'm unfamiliar with the process for Steam. If I continue working on the game and it eventually gets to a more robust state I can be happy with, I might move it to Steam. For now I prefer the casualness and freedom of Itch. 

Optimisation is on the list, I'm considering changing the physics based destruction to something more akin to Pawperty Damage. Quit button makes sense. I've had requests for a sandbox mode, I might not implement all the functionality you mention but at least flying and no timer would probably make sense 

Thank you very much for your interest! I don't have any support options, this is just a side project I want to do in my spare time in addition to making renders. That also means progress will likely be quite slow, so don't hold your breath 😅 I'll probably share most progress through Bluesky.
