Some things in Vicious Orcs puzzled me a bit. At times, locations in the dungeon diagonal to you were not visible. I tried to go in those diagonal directions. But I was prevented. Every time I picked up gold, yellow squares would fall down the left side of the screen and pile like a Tetris.
There were also some cool effects in Vicious Orcs. The screen would slowly fade to black on your death. The app would also move in a direction it thought you might want to go. I would try to go left. It was blocked by a wall, but the app would move me left and down. Sweet.
