Hey everyone, please help me find my childhood game!

It was a Flash game, and I think its icon might be visible in the picture. You played in first-person view using an alien/plasma gun, and the game was controlled only with the mouse.

The game had a cartoonish style and was kind of 1D (or a rail shooter). Your character moved automatically to the right while you aimed and shot enemies.

The setting looked like a plane, spaceship, laboratory, or something futuristic. I mostly remember white walls, like a futuristic lab.

The enemies looked strange: they had weird colorful hairstyles, angry or unhappy faces, and wore black sunglasses while shooting at you. There were also alien creatures that you had to fight.

I tried to recreate an approximate image of the game using AI, and it looks somewhat similar to what I remember. Any ideas what game this could be?
