I like your game a lot. It was quite challenging to get all resources for the rocket together - even on mid-level (started with the hardest mode, soon figured out that was no good idea, and step down to middle). The graphics, the audio and the upfront tutorial - everything fits together nicely. I also noticed a lot of little details - the best indicators for the passion a developer dedicates to his work.
I can image this also being a good mobile game - it has lots of potential.
I have one suggestions for improvement: Having two consistent, distinctive colors - one indicating only "good", and another only "bad", would make playing the game more fluent (the color red for example in your game can mean both - often "bad", but sometimes "good" - makes it hard to grasp the whole situation visually, with so many elements involved).
Overall I really love your game - great work!
