Some dude decided to make his own Ghosts and Goblins, and although it's not a full game yet, he did a great job with the first level.
And the technical atmosphere is very professional. See that glare in the corner of the screenshot? That's not because this was a photo taken of a television screen. What you're seeing is a screen filter that was inserted to help immerse you in the gaming days of yore.
Of course, that's nothing compared to the authenticity of the music and sound effects. Anyone who's ever been in an '80s arcade is going to feel right at home playing this game.
I can't say the game is as hard as it's inspiration (at least on the first level). For starters, there's no red demon.
(This isn't Locomalito's only game. He's done a lot of other amazing shit, too. Treat yourself with some expertly crafted arcade culture!)
