I wanted to give you the full five stars but I was put off by the "boot strapping". To be perfectly honest, I haven't the clue what it is and how to work it out because the doctor's explanation are incredibly vague. I was frustrated and after jumping on the clock, tossing it, jumping on it-picking it up-jumping-tossing it, and pressing all of the keys on my keyboard like mad I still couldn't find out how "boot strapping" worked.
If you're planning a sequel(and for future games) try making essential things like this a tid bit more obvious.
