Will be awesome to have in Platform Builder a comment option.
For example
//If health is less than 0, kill the player
if health <= 0
{
lives - 1
}
Will be good that the error detector doesn't detect this as an error.
Another idea is to disable parts of the GUI. A menu that you can select which parts to disable or enable, also this can be done with commands
For example, if I want to hide score, hide the time, hide the health, hide the ammo etc.
