Super cool level. My only complaint with it is that there doesn't seem to be much indication that it isn't an endurance challenge, but other than that, I enjoyed it.

The conceit of the level, once you figure it out, is super fun. The answers aren't always intuitive, but it's fun looking for them. The 8th chamber I didn't actually find all that bad; there's a progress meter in the background that shows you what you've done right and resets when you do something wrong, and all you have to do is experiment until you find the right combination. Realizing that the title is an instruction and not a description was one of my favorite parts. I also like how the deco gets more vibrant and lively as you progress, and the finale is executed really well, where you can just exit the lab instead of going around endlessly. And then it's super impressive from a technical perspective too. The way it just keeps looping around endlessly or stops your icon in place if you go through it in practice mode or saves when you've beaten the level and remembers it after you restart; all of those sound like they shouldn't be possible in a classic level, but here we are. I'm surprised this wasn't given a mythic rate with all the cool stuff in this level.

If you haven't played "Experiment" yet, you're missing out on a lot. Just make sure you go into it 100% blind. You won't regret it.

What a behemoth. Innovative, incredible, and simply one of the best experiences I've ever had playing a Geometry Dash level.

Watching a playthrough on YouTube doesn't do "Experiment" any justice. Its premise and concept is impressive, and while a level like AudieoVisual's "IN FI NI TY" may have been one of the first to dive into the whole "breaking the cycle" gimmick, "Experiment" manages to push this to its limits and surpasses boundaries with how it's structured and formatted. I don't think I'll forget the moment when I first played this just after it came out — completely blind — only to be wholly surprised when I "broke" the first cycle. It's an amazing level which excellently communicates its ideas; it never explicitly holds your hand or instructs you on what to do, instead leaving you to "experiment" and come up with interesting ways to leave each stage and move onto the next.

Going into it blind is honestly one of the best things you can do. Sure, that one ship section might be a little annoying on a first playthrough (I remember getting stuck there for a few minutes when I first reached it). However, the level does sneakily provide you a hint in the part preceding it. "Experiment" is probably one of the most original levels to come out in a long while. I don't remember the last time I had this much fun playing a level. Solving each stage's puzzle is really exciting and the way you complete the level is perfect.

Before reading this review, I highly recommend playing this level if you have Geometry Dash. If you don't, ask a friend if they have it and play it on their device. You definitely won't regret it. I also deliberately wrote this review to be pretty vague if you don't know this level so if you want to understand this review you gotta play the level lmao

experiment is the most forward-thinking and unique level of 2.2, at least gameplay-wise. The way it uses triggers to create unique puzzles that you have to solve in order to progress to the level is absolutely amazing. I'm not gonna say this is how gameplay should be done in a geometry dash level, but it's a near-perfect example of what gameplay in 2.2 levels COULD be if creators weren't focused on spamming obstructive flashy effects, and instead focused on utilizing triggers to create memorable gameplay. The only reason this level isn't a ten is that the clues for the ship orb part were poorly placed, and the last part is not as good or memorable as the rest of the level. However, the way you have to complete the level at the end is absolutely genius.
