Stupid Invaders is a pretty game for certain. The backgrounds are detailed, the character models are superb and the animation is silky smooth. The game features a full hour of integrated cinematics triggered by certain actions or played between scenes to advance the story. As beautiful as the graphics are, they don't hold a candle to the sound. The background music mixes perfectly and never overwhelms.
Sound effects are also very authentic to the cartoon canon.
Most impressive is the voice work. There are few games on any platform that can hold a candle to Stupid Invaders. The pacing and characterization are near perfection. Speaking of characters, you get to control them all. Etno, Candy, Bud, Stereo and Gorgious all have their own wacky personality.
