very cool take on the theme, had a lot of fun with this one! i thought it was going to be a shorter game due to the amount of levels on the select screen, but there was a lot to go through, which is very nice! having a lot of different subjects covered in this was cool to see! maybe categorizing the levels by similarities of studies (astrology, biology, sociology, etc) would be cool to see in terms of how well you know each specific study, but nonetheless the puzzles were a nice brain-teaser! congrats on the submission!
