This looks like a really interesting game, and I loved the concept, but after two tries I still couldn't understand what exactly I needed to do. I think I managed to complete the tasks for Rocket 1, but I wasn't able to figure out how to complete Rocket 2's tasks. I found it difficult to distinguish the actual objectives from the lore and technical terminology.
I also found the fuel minigame a bit frustrating, although that may just be because I'm bad at it hahah
Other than that, I liked the sound effects. I think they really improve the atmosphere of the game.
