Neat! I definitely think you could benefit from a better tutorial. When you first start its difficult to understand whats going on and what tools fix what problems. I also think some sort of visual indicators for each symptom would help you locate problems more easily as it is difficult to understand how they relate in a long list. The art was really nice and pretty funny (especially the weapon arms). and the sound design and music were great (the robot voice was a great touch!). I would suggest would be the cursor placement for the tools consistent (like always in the top left) as sometimes I couldn't tell where my cursor actually was and also adding some indicator for a part being missing/removed.
