The theme is great but doesn't have protagonism in the game. Maybe you should have added a game mechanic around teaching them things. Because this game is just, click and wait.
The gameplay is really satisfactory. The movement is really great.
The map is "Really, really big". But that is not a problem because you have nice movement making that not a tedious task.
The art is kinda random and doesn't have any concordance, but it's ok as a 2-day game.
