Alright, this is the developer's comment about the bug he forgot to fix.
First, there are times that the player can still get hit when its health is already 0 or below. Even that, the number is supposed to display negative numbers. Another thing is that setting the cursor to none was a previous intention. However, due to some complaints, I removed those actions. Turned out that there was one hidden action when the player clicked "Yes" on the Continue button, the player's cursor set to none. I forgot to remove that one last action from the code.
