I first got this game many years ago for my smartphone. I had my fun with it, but the controls never fully caught on for me. I think you can use a controller when flying, but building on a touchscreen felt off to me. As such I was hopeful for the PC version. It could have worked just as smoothly as Kerbal Space Program or Besiege. Sadly that doesn't seem to be the case. There are some minor improvements/changes, but ultimately it felt like I was playing a mobile game on my PC. It felt like I was using the same GUI and the same controls, main difference being that I was using a mouse instead of a finger. This isn't really a critique of the game though, but more of a warning that this is a lazy port of a mobile game. It's a game I like, but I probably wouldn't have bought it again for PC if I had known this.
