Even though the developers probably won't see this, geometry dash is a great game overall. The free version has normal levels, and the full version has levels like "fingerdash" and "deadlocked." Also, there are a lot more. My only complaint is that when you beat levels like Clutterfunk and all of the free levels, Clutterfunk, and the other insane levels, it's hard to move on to higher levels that are supposed to be easier and harder. Even if you aren't playing on an insane level. Similar to geometrical dominator and blast processing. Those aren't considered insane, but they are hard to finish when going from clutterfunk to one of those two levels. Also, electrodynamix should be rated as a demon.
