I just started playing GlaielGamer's new game, Closure - http://www.newgrounds.com/portal/view/48 0006
The idea of falling through the unlit spots is damn similar to my game I've been working on, which can be seen here: http://www.youtube.com/watch?v=KGxXiI31V Gc or played here (hold tab for controls): http://spamtheweb.com/ul/upload/010209/6 7521_galaton.php - please remember it's unfinished at this point, and the third level doesn't work.
Now, I know the idea between the games different, but the whole concept of falling through the level if it's not shown is very similar.
I'm not saying he stole my idea or anything, I'm just wondering if I missed the boat on my game being considered original, or atleast the fall-through-the-level concept being considered original, even though I started the game before Closure came out.
