I approached this subject during a review of Marble Saga: Kororinpa for the Wii a few years ago. For those that don't know, or didn't infer by the game's title, in Marble Sage: Kororinpa you control a marble. You do this by tilting the Wiimote. The game overall is great and reminds me of the table-top board game Labyrinth, although this electronic variant of the game has you rolling not just on a flat plane, but down hills, tubes, cliffs, etc.
The moment where I found myself faced with this moral conundrum occurred relatively late in the game when the difficulty was ramping up. On one particular level I noticed you could tilt the world and drop your marble from the beginning of the level to somewhere into the middle (or even later) by rolling of the edge and catching yourself by tilting the world flat some distance below. So...should I take advantage of this exploit? Was it what was intended?
The answer I arrived as was that you should take advantage of whatever structure is in the game. If the designer didn't create a limitation, by all means, exploit it. Case in point, in the follow up to this title the developers instituted a 5-second fall rule. That is, if you fell off the board for more than 5 seconds you were placed back at your previous save state.
It's up to the designers to create a structure to limit our abilities as players. It's up to the players to refine those abilities and create new ones to destroy the game design. Hopefully the game testers have already been taking advantage of these exploits and have sent the notes on to the developer so they can be fixed.
