This game reminds me of the aforementioned. It is a little rough around the edges, but still gets enough of it right to keep playing. The controls and interface do seem a little "wonky" at first. But given time and trying press and hold on in-game objects starts to simply things as you go along. I was also concerned with the IAPs. After contacting the developer, I have it on their authority, that the IAPs are not necessary to complete the game. I found this to be fairly true with only minor grinding to find good upgrade drops; which are comparable to black market purchases. The only thing IAPs are a must for, is buying a space station. But that only gives you rather unlimited space to store all your loot. I dont see not having this option as heavily effecting the gameplay at this point.
