"Geometrical Dominator" is a level that could not have been a better introduction to the 2.0 update. It's a level which bursts with personality and charm and I personally thank it for being a key inspiration for "Vanilla", which rightfully secures its place as one of my favorite levels of all time. It's a level that introduces so many key mechanics added to 2.0 but never feels like it's excessively dumping all of 2.0's new features onto the player despite how much it manages to showcase and cram within such a short amount of a time. Within the first few seconds of the level, RobTop already displays a considerable proportion of the countless possibilities that update 2.0 paved the way for. There's more than 4 color channels, proper in-game text that you can edit, moving objects, novel block design, new cartoony clouds, moving monsters as well as rainbow galore, and that's all within the level's first 10 seconds. "Geometrical Dominator" acts as an incredibly creative, genuinely awesome and dynamic way for RobTop to showcase 2.0's full potential.

There's no other main level that's able to keep up with "Geometrical Dominator" in terms of color and whimsy; of all the main levels, "Geometrical Dominator" is certainly the one that's least afraid of experimenting. There's so many different and varied environments and features that it attempts to portray. It starts off with a monotonous grassland landscape but then suddenly pops with color as you transform into a robot. There's a section in which you navigate through a dark castle before you then find yourself leaping amongst rainbows and clouds. There's the infamous dark memory section that I personally really enjoy in spite of its pretty notorious reputation. The level finally ends with you exiting through this mechanical, factory-like, yet still vibrant setting, which provides a stark and drastic contrast to the grassy, verdant beginning that you're introduced to. "Geometrical Dominator" is a level that takes you on a journey that truly opens your eyes to how much you can accomplish within GD. Sure, you could argue that it's not extremely cohesive, and it might not be, but that's really the whole point of "Geometrical Dominator". It's an exceptional level that really works to show off how much could be accomplished with 2.0 (even if most player-made levels at the time couldn't successfully capture the unharnessed potential the updated editor now had).

In my opinion, "Geometrical Dominator" is probably one of, if not the best main level in Geometry Dash. It's a fantastic and creative main level that truly shows off the editor's potential. It's extremely fun and I appreciate how experimental it is in its approach to introducing new 2.0 mechanics; it's a level that's the equivalent of throwing stuff at the wall, but somehow it comes together to form an excellent and well-refined final product.

(Also it led to the creation of "Vanilla" so I obviously hold it in high esteem).
