Thank you for the play through.
There are a few mechanics in the game that I failed to represent clearly or make sense of. One of which is landing the ship on other planets by activating the landing gear, and rotating the ship in the correct orientation for a proper landing. This allows you to mine materials off other planets, pause the use of oxygen, and give you a point for relaunching (in turn, saving fuel). P.S. Ditching the ship gets rid of whatever mined materials you have collected.
I definitely have a lot to improve on when it comes to game design. Thank you for your response.
