Haha, agreed. I really wanted to add a controls page on the pause screen but just ran out of time.
Controls are posted on the game description page on itch though. Not much to it though. Rotate using the arrow keys, spacebar goes forward, tab changes camera.
All the cutscenes are literally just using the built in animation player. I made a few animations for the player to repair things in place, duck and cover, looks surprised etc. But really all the movement around and everything else was just the animation player cueing various actions to take place in order.
