Whether this is a new project or old ones from back in 2014 or so when Rublock5 was an active creator, Rapid System is a nice little callback to the "good old days" of Geometry Dash. Even for the time it was likely made (1.8 or 1.9), it's quite simple and draws pretty heavy inspiration from Theory of Everything 2, using large chunks of small invisible squares, vertical blending glow pillars and lots of other timely decoration choices. I don't have too much to comment on here due to how simple this level is, but I do appreciate how concise each part feels. Every part has its own defined idea or stylistic choice that it centers around - the aforementioned invisible square structures guide the player through a gravity portal corridor with a ship, one part uses many identical vertical 3x1 blocks to form a little staircase for the cube, and another uses slanted pillars to direct the ship between some spiked structures. The level as a whole flows nicely from one part to the next, and quite a high level of understanding of general design criteria is shown for the time. This is a pretty impressive project for the time it was (likely) made in, and I do hope it receives a Star Rate. Nice work!
