$-$There should be $4$ LEDs and $4$ buttons for sequence remember challenge

$-$Game should has $10$ levels $($details below$)$

$-$There should be $1$ LED to display the current level $($details below$)$

The game works as ;

$-$At the start, all $4$ LEDs should be blinking with $200$ms delay

$-$Whenever a button is pressed $($any button$),$ the LEDs should be turned on for $2$ secs$.$

$-$After that, all LEDs should turn off, and game starts after $1$ sec$.$

$-$At $1$st level, a random LED blink will occur in one of the $4$ LEDs, then game waits the user input with button

$-$If the button press is correct $($with respect to LED$),$ the level will increase to $2($E$.$g$.,$ if the $1$st LED blinked, and user pressed the $1$st button$)$

$-$At the $2$nd level, $2$ random blinks will occur. After the blinks, the user input will be waited. If buttons are pressed correctly according to blinks, then process will continue to increment to level $10.($E$.$g$.$ if blinks are occurred in $2$nd and $1$st LEDs, the user should press $2$nd and $1$st buttons in same order$)$

$-$In each level, one more random blink will occur.

$-$In each level, the brightness of the indicator LED should be increased.

$-$At the end of game, fail or completed, game should jump back to start and wait user start with blinking LEDs $($same with starting condition$)$

Please give me Arduino code and circuit design
