Unwanted behaviour when keys are pressed too quickly

[BOAScripts]

example:

direction=LEFT
if 'UP(or DOWN) & RIGHT' pressed too quickly

• trigger gameover() (when snake.length > 2)
• reverse snake direction. (when snake.length <= 2)

Reason : It has to come from the fact that the eventListener of the keypress is not subject of the timing event of the displayFrame.

Possible mitigation : synchronize the timing event between keypress & displayFrame.

Solution : Define a boolean (canPress) if key can be pressed or not.
Set to true once per frame.
Set to false once a key is pressed.

Result : it feels like some directional inputs are not registered.

idk what to do to get a better feeling
