Note:
“prince megahit” works on version 1.0. For version 1.3 and 1.4 it’s “prince improved”.
Another observation: when using N/U/H/J to browse the level, you can use K to kill the guards, but they don’t stay dead – they will come back to life if you visit the same screen again (in real life or while “browsing”).
Also, if you kill an enemy, then quickly browse away from the screen and come back to it, the enemy will come back to life too. It seems that the game only registers killed enemies when the prince physically leaves the screen – if you leave it and come back, enemies will not come back to life even if you use U/N/H/J.
Warning: Using K to kill the skeleton can freeze the game!
