You should have a mechanic to befriend other classmates to get powerups or a rivalry system with the class nerd for an extra challenge. Really neat idea! :)
That's a neat idea but it was hard completing the level even if I knew where the platform was. Maybe have the platform fade for a few seconds before disappearing, and adding blocks that explode, slow you down, or reset your progress can make it spicy.
Cool concept! You should make more harder levels expanding on the triangulation concept. Most of it were easy to figure out once I understand what triangulation is.
