• To make a functioning 3D game in 7 days is quite a feat, so well done!
• Procrastinator 9000: "I feel heavy..." GOOD. That's for making me do all the work!
• Why Yaks? I mean. Just why? I never understood even when I finished the game.
• Why is a computer system... hungry and sleepy? (Theory. The job has been outsourced to me and someone is conning me into doing it for less pay.)
• The interaction with items is a bit clunky. It was a bit frustrating when I had to put fuel in storage and burn waste. Making me hate Procrastinator 9000 more...
• The ship did not explode.
• Great to see Nathan's Dialogue Manager in different games :)

I honestly thought I was going to chase yaks. Instead I am an errand boy to a lazy computer system :(

Overall, I like what I see here. It's a little rough but stuff like what is mentioned can be improved. You built a ship with the ability to fly to other planets and that's awesome! Outside what others have mentioned about same tasks here are some points of contention for me:

1. Controls - No need to walk left/right if you can just rotate in those directions. At some point I ended up not even rotating the player because it was just too confusing and easier to just walk in a direction. The rotation is the opposite of what comes intuitively for me. Also right clicking to jump seems strange?

2. UI - Needs a grammar check, quite a few typos

3. Sounds - Needs sounds to help build the atmosphere. If you have technology, some simple beeps and boops would help make the ship feel more alive. 

4. Visuals - When in Space I would expect to see some stars? Perhaps a skybox that is rotating to simulate movement?

A lot of points I was going to touch on have already been mentioned by other commenters: the tasks are repetitive, there is a lack of unique tasks, the camera system is a little weird.

Overall, there's good programming and thought behind the game, but it leaves engagement to be desired. A potential solution to the issues with engagement, other than offering a wider variety of tasks, could be to flip the goal of your game: instead of "how fast can you do these tasks," maybe it could be, "can you do all these tasks before your ship explodes?" Then the player feels more urgency: every time they pick up fuel instead of engine waste, the timer ticks down a little more. Then, as the game progresses and more tasks are introduced, suddenly the player has to manage their time a lot more efficiently. As for fixing stuff with the camera, my only issue was with the direction it rotated: if the player is facing forward and they want to look to the right, they may think that they should press E because it is to the right of W. Instead, the player must press Q, which is to the left of W.

With that said, you have my honest feedback, and I hope it is helpful.

The game is good. It is not getting too boring while playing it, but it is on the edge of becoming it, so finishing on the third level is a good decision. Otherwise, this should have at least more visual/audio feedback provided for the player to keep him engaged in the playing process. 

Also, I think there should be done some improvements about camera. I don't think it is the best decision to make isometric camera with third person WASD controls. It just feels wrong, especially when you have to rotate the camera. At least, the angle must be adjusted the way it is not that confusing for the player. What I would do is to change controls to cick-to-move, camera is still isometric and follows player but with fixed angle.
Dialogue system is good, however I didn't really found myself in situation where I had to turn on/off the gravity generator (besides repairing this generator) (What about yaks getting angry and turning off the gravity to make them calm down?)

I already mentioned that playing this for a while makes it a bit boring process. For game jam it's alright, but as a long-term solution I don't think it is. The game loop might be the same, but maybe more troubles that could happen to the ship while traveling to the planet or through space?

All-in-all, I like this game. It is pretty good. (Beat in 900 and something seconds 😅)

The rotation makes me dizzy at times. Maybe try reducing rotation speed. The text boxes could use some styling up, looks bland at the moment. The tasks were wonky at times. It was hard to put fuel in storage.  Also there is a lot you can do with this other than just picking and placing objects. I couldn't find a use for jump, but it was fun.
