Within the now relatively short period of the games existence from 1.0 to 1.4 its absolutely miraculous how GD was so densly populated with phenomenal creators. M2coL is of course most well known for the first officially rated demon in the game, Demon Park, a level so groundbreaking it still stands to me as a symbol of a great Top 1 Demon and while psychic escape doesnt live up to its older brother in recognizability, popularity and influence, it certainly can stand on its own. The structuring and flow are impeccable it really feels like a complete piece. The colors add to the level significantly which you dont often see in older levels. It progresses from the very desaturated colors of the first half to the distinctly more vivid colors in the second half as you get closer to the end, with the final climb being the culminating point here. The update 1.4 is one characterized by a turn to something slightly heavier for Geometry Dash. All the new assets and the song, Clutterfunk, stand out as being more industrial in nature than any other updates. M2col obviously takes advantage of this using the combination of these elements along with awkward, tight, hard to predict gameplay to create a level thats suprisngly intimidating to this day even with the general communitys skill level at a point way higher than where it was 11 years ago. As a last point it should be said that while it is minimalist for todays standards it stands the test of time very well and id consider it much better than most levels even if it were made a week ago. I hope more people decide to delve into the past of Geometry Dash, not only are the levels there often just as interesting, funny or preplexing as in modern times, they can also be just god damn mothafuckin good. Thank you.
