2000s flash game where you're thief hiding from lights

Many years ago I played a stealth platform game where I was a thief. In the game, it was night or at least dark and I had to sneak toward the goal inside a museum (or something like this) and avoid getting caught from the guards the lights and the lasers by hiding in the shadow of the wall behind (by clicking a certain button on the keyboard). If you touched any of these the alarm sounded and game over. The mechanics are similar to the game "Dude Where's My Pants". There are more levels in the game: outside and then inside. The character I controlled was a stereotypical burglar. The animation was 2D and smooth, more late 2000/early 2010ish, it lookes like a tipical flash game. The music matched perfectly to the climax, I remember a contrabass playing and some others in the background, but mainly a contrabass. It's not Bob The Robber. I already asked on Reddit, but nobody can't find this game yet. I used to play it on Spele.nl. Can someone please name me this game? Here's a drawing I made of the game as how I remember:
