10/10 level in my eyes, would give a 100/10 for gameplay if we could. The best top 1 geometry dash didnt have (not counting the few seconds it was on before the Hacked Verification Slaughterhouse). Cherry team made the perfect level for a Geometry Dash player to look at and go "wow, this is absolute madness," not relying on "hype moments and aura" as they say. Most victors of firework claimed it was a very fun and enjoyable level, and this is supported by the disproportionate number of victors it had compared to other levels around its difficulty (this is a bit harder to prove now that its been on the list for a far longer time than some of the levels around it). The level has a newgrounds song, isnt excessively laggy, and is a standalone level with a creative design. The deco is solid, definitely not the best aspect, but it does what it needs to do to serve the theming and atmosphere perfectly.

But the gameplay is so so good its mindblowing. A short predrop creates instant intensity, making it far more fun to watch and play when compared to the drawn out and often nothingness of slaughterhouse, and oh my god its just so pleasing to watch. The flow of the level is incredible, some of the duals like the ship and ufo are so satisfying and you'd never think youd see something other than wave spam and straight fly in the economy of top 1s that Fireworkw as made in. The most iconic part of the level, the orb ship, is incredible as well given how the song goes and the position of the level its in. Its like trying to defuse a bomb when it has a minute left before detonating, so nerve wracking. But the best part is the cube sections. Those cube sections, like around past 50 or something like that, are the best Ive ever seen. Incredibly well synced, themed, and pleasing to the eye. A visual masterpiece of gameplay, something most other levels of its caliber at the time failed to achieve.

Firework is a masterpiece of an extreme demon. One of the most underrated levels ever, period.
