I remember a 2d math game that I played in 1st or 2nd grade, with Pachelbel- canon in d major playing in the background, the premise of the game was a charachter would walk forward and encounter puzzles. For example there would be an apple hanging from a rope, and on the apple would be a simple addition problem. You had to solve the eqation to make the apple fall onto a button that would cause a drawbridge to fall down, giving your character access to the rest of the map. At the very end your character would enter a castle with 3 treasure chests. In one tresure chest, you would ide a unicorn, in another you would go scuba diving, and in the last one, you would go to space. I have tried to find this and failed, I hope you can help me find this strange 2D math fro the early 2000s.
