Mac Version. I don't if the left shift key will work on Mac. You can now fly the helicopter in Nazilla (if your left shift key works)! I've also made quite a few other improvements such as the truck stopping automatically when you jump out. Vote for me on Greenlight, there's a link in the main menu of the game, thanks!
The shift button is fixed
Thank you :)
Truth is I didn't do anything different concerning the shift button so maybe something was a bit odd with the previous build output. Thank you very much for writing and letting me know because I don't have another way of knowing at the moment.
