Help identifying a "gamemaker" game

[finisher]

There's a program called gamemaker that you can make...games.

I saw this youtube video with it where it was Bass (from Mega Man 7, etc) fighting in some custom stage and I think I remember him fighting in a Doom-theme stage (with Doom enemies, etc.)

Might anyone be able to locate the youtube vid or where the game is available for dl?

EDIT: It's actually "game maker", with spaces. And I'm kinda doubting if it's really using the Game Maker engine. It was something you can play online directly from a web page.
