Added equations and adjusted the pause menu

Hello again, Jaessie is here again with the math test game

I've just updated the game so now there's equation & expressions instead of only expressions to solve.

You can try the game here Math Tests.

Plans for next update:

I plan to add music & SFX to the game, Also, I plan to change the background and style of drawing.

These will hopefully be implemented in the next update by the 11th of October 2025

Thanks for taking your time reading this & see ya again.
