Problem with keys

Hello, I am new to construct

I have made the character move using the keys A, W, S and D. However, I noticed that if you press several of these keys simultaneously, the character does not move. Is there any way to solve this problem?

I would appreciate someone's help.

Add Else condition to events.

Is A key down : move left

Else
Is D key down : move right

Else
Is S key down : move down

Else
Is W key down : move up

I don't know what to explain. Only one key will work at a time.
