Being a player or a creator isn't the same. A player can do anything if he tries really hard. Anyone could get all of the player achievements with a lot of efforts. But being a creator isn't just about making amazing levels. You have to get noticed too. It doesn't depend just on your skills, but also on luck. A lot of luck. That's why people hate the star rate achievement. A lot of good creators deserve it but haven't got it.
Yes, while getting the achievement takes a lot of luck, there are strategies you can take to get it noticed. Some people may spend only a couple weeks on a level and get the achievements, some longer. However, I've played for 2 years and I'm not even halfway to the 10K Stars achievement, and I would even have the 50 demons achievement if it wasn't for old, free demons. It takes ages to get some current achievements, however excellent creators barely get any, why should they not get achievements because other people complain they can't get it?
I know, it's very limited when it comes to variety of gameplay, and it is hard to sync because of that unless you have a very fast song. At least it the cube mode, it is very useful for ship.
I agree. It should be added when RobTop makes the feature system as best as possible, so every creator that makes good levels gets them featured. Then when that happens, there should be creator achievements like "Get an epic level," "Get 10 CPs," etc. Believe they are shards of power.
