Wow, creative concept. At first attempts I had suspicion that once you got something wrong, the next choices will be wrong. Turns out the sequence is resetting so I have to click from the beginning again. In my last run, the patient #2, #3, #4 have the same problems so it became easy for me to clear all.
If you want to hear suggestions, please add visual cue of when we select correct cues. Example: Clicking the correct tool will highlight them with green color. And when I choose wrong, all highlight is removed.
