A Place in Space by lokijki.

It might be partly because one of my favorite games of all time is Shoot First by Teknopants, and that this game is incredibly reminiscent of it, or any number of biases, but this game is INCREDIBLE.  The theme is well executed in that everything does take place on one screen, even the title, through use of shadows to cover up the portion of the screen that is unavailable at any time.  Then you blast your way through an alien-infested room with perfect controls and a door opens up.  You walk into the next room, no big deal, blast away some more enemies, sweet, but no big deal, and then… And then the door that had just locked behind you  opens up, and you think, “Damn, I don’t want to go back into that room again, but whatever.”  And you walk into the room and as the shadows recede, you realize, “Holy crap!  This is an entirely new room!”

Pure genius.

On top of that,  the graphics are simple, but marvelous.  The amount of screen shake at points of impact is amazing, and the RGB-positions (or something) of all the sprites shift when the screen shakes.  It’s super gory, super addicting, and super worth checking out.
