I bought the game over steam and I simply just don't like it. For me, it violates all my expectations for a smooth UX (User Experience) with an effective UI (User Interface). There are too many restarts required because the Z key or space-bar does not work as published. There is no reason, after a relaunch, all else being equal, they then work. That is just too much time to repeat something that should have worked the first time.
I can enumerate all the violation of good HMI (Human-Machine_Interface) design, but that would do nothing, as I am sure the developers are busy working KSP2 for all those players that just don't mind getting by with the design they have.
I appreciate your time to consider this request.
Thank you.
