I haven't noticed that it's supposed to be an RTS.
I used the term fairly losely, the game is about raising up numbers of Dyson Flowers and attacking other asteroids and taking them over, so I felt the RTS label kind of fit.
Does it offer anything more than Dyson? Aside from more levels, of course...
Yes, albiet the standout features are really the polish that's been added and the additional levels. One key difference is the attrition factor; your Dyson Flowers will die off after a certain amount of time to prevent you from raising trillions of them and just steam rolling the game - you have to select very carefully how to play. Also of note is the Procedural Level Generation code is almost entirely bulletproof - no more large, un-navigatable gaps between asteroids making some levels unfinishable.
