Reminds me of the start reactor/simon says task in Among Us. Nice job though, I like the sounds, and I think pressing the buttons on your keyboard is more fun than using the mouse. It'd be nice if you could scale the game window up some more (change the "Test Width" and "Test Height" parameters to double or quadruple the window size, they're on the same settings page as the window size) and maybe make the squares take up the entire game window since right now they're just in the top left corner, you could do that by making the squares bigger or making the base resolution smaller.
