Math Classroom Challenge 1.85 with a new challenge: the airplane

Hello there. We have uploaded a new version of Math Classroom Challenge: version 1.85. The most important new feature of this version 1.85 is the introduction of a new airplane to the “Save the seas” scenario. This airplane will appear after some time playing and will be flying across the stage. This airplane will throw plastics to the sea from time to time. The radar indicates the presence of the airplane with a black spot. And these plastics are indicated by a red spot. Also remember that the standard plastics are indicated in white, and the walls in blue. Collecting the plastics dropped by the airplane gives more points than the standard plastics, but you must finish the standard plastics indicated with a buoy and a white dot in the radar in order to finish the game. Take a look at the manual in https://mathclassroomchallenge.com/manual/ for more info. We have also solved some minor glitches, and added some enhancements to the game. Thank you for your support, and don't hesitate to ask any question you might have, or any improvement you'd like to see. Regards!
