The game of blocks falling from the sky has been around forever.
The game of shooting stuff before it hits some other stuff has been around forever.
The game of robots shooting at other robots and then exploding has been around forever.

The game of avoiding the blocks that fall from the sky has been around almost forever.
The rest have been forever. falling blocks game wins the originality because its the least unoriginal.

Xextredge contains so much hacky crap that I'd love to make available to the rest of you, and will soonish. But uh, for a month long contest I'm really impressed with all the entries.

My personal favorite aspects (from a technical standpoint) are the pseudo-HUD in TD and the difficulty selection in The Reject.

He didn't have an entry. Neither did lafe. Read the topic.
