Okay, so the point is actually to **** me off.
No, the point is to make you realize the game world is not flat by not allowing you to simply walk over tables and cupboards as if they are decoration painted on the floor, which is what almost every other game does. What do you suggest anyway?
Edit: Sorry for being rude, but it makes abo****ely no sense. Do you also put up a prompt when going near a powerful enemy? With a penalty if you tried?
Walking near enemy is not the same nor similar thing as climbing on top of kitchen table.
Edit2: You're not even consistant, as the prompt before walking on acid for exemple doesn't take any time. My guess is that in you're coding, you're putting the prompt up after the game processed your move. You should fix that.
Yes, it should be consistent.
