Also, well done Mrmath, I wouldn't of gotten that.
Geometry Dash Trivia

Sonicwave Infinity?
Wrong. Sonicwave Infinity has already been made, it's just in the middle of being verified by Sunix although Riot said he will try verifying it during the summer when he has more time.

Jesse Valentine. Not sure if that has anything to do with Geo Dash but whatever. Kinda related I guess, probably belongs here, we don't have some "Music forum" or something
That gives me a question idea, which I'll put at [DEMON, 10 stars]: What are the real names of dj-Nate, Waterflame, Step and Dimrain47? They shouldn't be hard with a bit of research, I will give 1 point for the first, 3 for the second, 6 for getting 3 correct, and all 10 if you get all 4 names.

You underestimate me. I'm a Newgrounds music artist myself so I am friends with some of these people you know.
dj-Nate: 'Nathan Clark'
Waterflame: 'Christian Krogsvold'
Step: 'Stephan Wells'
Dimrain47: 'Clayton Judd'
Please have more questions like this one, please? xP

That's his YouTube channel, yup! So I now need to give you 10 "stars" from our Trivia Game.
Another question I will ask, worth 20, will be: name 2 new objects introduced in each update from 1.2 - 2.1. ie. 1.1 introduced Mirror Portals; what were two objects introduced in 1.2, 1.3, 1.4, etc?

ICONS DO NOT COUNT. If there are any updates which introduce only one new object, so state.
Also, say the levels which were introduced per update as well, and which feature was added.

1.2 - Cycles was made and Ball (does that count as icon?) was introduced.
1.3 - xStep was made and Leaderboards were introduced.
1.4 - Clutterfunk was made and don't know about objects... sry...
1.5 - Theory of Everything is made and copy/paste in editor.
1.6 - Electroman Adventures and Clubstep both released.
1.7 - Electrodynamix and speed change in editor released.
1.8 - Hexagon Force and dual character introduced.
1.9 - Blast Processing and Theory of Everything 2 released.
2.0 - Geometrical Dominator and Deadlocked released.
2.1 - Fingerdash and Spider introduced.
Can't wait for 2.2 even though nothing in will apply to me. The collaboration system won't work for me cause I suck at making levels. The Demon Coins is a nice idea, although I'll have 0, and also a 'nill' from me for "community-created icons" because I can't do digital art.

Not exactly what I'm looking for. For Cycles, I was thinking Gravity Ball mode/portals;
xStep introduced blue rings/pads and rounded black spikes;
Clutterfunk introduced mini mode/portals and sawblades;
Theory of Everything introduced purple rings/pads and UFO mode/portals;
Electroman introduced ice-style spikes and breakable blocks;
Clubstep introduced invisible (flashing) blocks as well as fake spikes;
1.6 also added Secret Coins along with those two levels and their features;
Electrodynamix introduced speed portals and backgrounds of the player's color(s);
Hexagon Force introduced dual mode/portals, inclined slopes, and certain decorative block types (example: final cube part);
Blast Processing first introduced wave mode/portal and "block-like" black spikes (if you know what I mean);
Theory 2 introduced invisible sawblades and (technically) mini wave;
Dominator introduced Robot mode/portal, moving objects and rainbow objects as well as triggers (final UFO part);
Deadlocked introduced keys, green jump rings, teleportation portals; text ("I like this part"); 2.0 added Vault and User Coins;
Fingerdash introduced Spider mode/portal, red jump pads, many new decorations. 2.1 also added mana orbs, Diamonds, daily chests, Vault of Secrets, Chamber of Time, Hall of Fame, Easy/Med/Hard/Insane/Extreme Demon ratings, daily levels and quests, shops; Demon Chests; Gauntlets. (jeez that was a lot).
I can tell you tried and you're correct for all of them, so you still get full credit. As for Demon Coins, I probably won't have any because of Demon rating inflation if you know what I mean (a lot of demon-difficulty levels get downgraded to Insane because they get low ratings by expert players like Guitar and Surv and Michigun, and same happens to Easy Demons which end up being Medium Demon difficulty or so). If only Neptune would update his xStep/ToE/Electroman v2 levels and maybe I could get a couple...
Collab system - same here.
As for community-created icons, I have ideas but I'm to shy/unconfident to try and share them
You.
