The graphics are really beautiful! Since learning is the objective, it would be nice to see more interactive elements that don’t involve getting a trophy. Also I’m not sure who the intended audience is, but as someone who stopped biology as soon as I had the chance in high school, this jumped a few levels. Perhaps it would help to have beginner, intermediate and advanced levels in subsequent developments. Overall, I do really love it and definitely learned a lot! Also if you could have multiple random scenarios or something so each time the player plays, they do a different kind of repair or adventure, that would be fun! If you haven’t already, I’d suggest looking to Carmen Sandiego and Cluefinders type of games for more ideas.
