Excellent core mechanic and impressive level/puzzle design, though a lot of rough edges that naturally come from it being a student project (I think) - twitch controls that don't really match the more leisurely animations, misspellings due to ESL, odd jump physics when on some moving platforms (particularly the two moving a short distance quickly in door 7), unable to skip dialogue if you accidentally talk to someone again. The black interact 'Z' can also be quite hard to see against the dark backgrounds sometimes.

I didn't like that you automatically enter key doors when you touch them if you have the key. I got 95% from missing two star fragments on the final level when I was inadvertently blown into the door without my choice.

If I seem to be criticizing a free student game a bit too harshly for lack of polish, it is only to help them learn as they asked for feedback. I still enjoyed my short time with the game and am giving it four stars, as despite all my nitpicking it is indeed free.
