I liked the strange concept of the game, I thought to myself "If space travel becomes cheap enough, transporting animals between planets makes sense". I just couldn't keep up with the repetitiveness of the game. I felt that it was well written and everything, but changing fuel is not fun and also not challenging, a timer and alarms would have helped make it more satisfying. The same with getting the cargo, it was fun that is bounced around, but getting it had no challenge, it would have been fun to chase the yaks around or maybe throw something at them to knock them out before grabbing them. The camera movement being locked to where the player is seeing I think it was a mistake, you should have made the character face the mouse cursor.
Pretty complex game to make for a game jam.
