Atari's Adventure - Redone NES Style

I thought about a concept like this half a year ago, but never made sprites for it.
Here I am with them now.
The square you play as has been upgraded to a knight in shining armor. It includes all equivalents of palettes you can find in the game.
The weapon that looks like a pointing arrow is now both a sword and a strange spear.
The keys are still keys, the magnet's still a magnet, and the trophy is still a trophy.
The bridge is also still, surprisingly, a bridge, and the duck-dragon looks more like a dragon.
