I suggest a new feature: The game will check to see if the following are ajancent to the screen: Grass, shallow water, overhead combos, layers, lock blocks, and anything else. Why lock blocks? In the oracle games, locked doors that are right next to another door will open when one door is opened. I guess that wouldn't be nessacary, but the others would be, especially with freeform dungeons. Also, I should check and see if this is the case in LTTP, because I can't remember a screen where shallow water spans 2 screens.
