What an amazing looking game. I would say you did a wonderful job here. The Straddle Carrier is hell to control and I can see that being the case in real life as well. The environment was rich and after I figured out more of what to do it became better to play. I would say there is quite a ton of controls that you need to use and using F1 for Help in a webGL version is absolutely counter intuitive as it takes you to browser's web help. Anyway, all in all, it is an amazing game and I am sure you could actually release this with some tweaks.
I will post the exact timestamp to my VOD later.
