Script is a really interesting level that makes use of a lot of effects that didn't see much widespread use until much later in 1.9. There's some flowing, horizontal pulses (mainly in the UFO about halfway through) reminiscent of creators like Funnygame and Ggb0y that would make use of them later on, and plenty of colour pulsing to make the code scattered around the level appear more glitchy. There's quite a lot of polish for the time, especially considering how new this method of using pulses was. The theming throughout the level is strong and consistent, and there's a solid amount of song representation done using a variety of glitchy pulses which works really nicely with the theme.

One thing that does show this level's age is the part to part flow. Aside from the overarching theme, there's plenty of very sudden changes with no suggestion from the song or gameplay (namely the flappy bird section). This is something that nowadays I find quite endearing and nostalgic, but it's definitely improvable and a sore spot with the level's overall cohesion. Speaking of the gameplay, it's quite basic and freeform, lacking much structure or player guidance. This is a double edged sword, as it allows more room for the set piece effects and backgrounds to shine, but doesn't really serve much purpose in the sense that it doesn't allow for any creative freedom in much of the structuring.

Script is a blast from the past from a creator I'm unfamiliar with, and it's great to see people innovating during a time of heavy editor limitations compared to what we have today. I'd personally love to see this featured, and will be checking out some of Gamer's other works.
