If you look at the game review by I Dream of Indie Games on Youtube, you will see that at timestamp 4:21, the face of the young engineer is revealed. His facial appearance suggests that he is quite young. We estimate him to be around the age of 15.
In this PC Gameplay on Youtube Uploaded by MontanaPLAY, if you pause at timestamp 13:10, you can see the scale difference between a cabin door and the Young Engineer. If the door follows the standard door height mentioned on Rustica which is 80 inches, then that would give us a conclusion that the Young Engineer’s height must be around 55 inches or 140cm tall. This estimate was further visualized using Hikaku Sitatter Height Comparison Chart.
