The gameplay is good, but I believe the game lacks visual and audio cues of actions taken by the player. I cannot know if the actions I performed have truly been done right and it makes me confused if I actually did them right. Looking at the altitude value I see that I am going higher, but no other element on the screen tells me that. This is the sort of thing that changes a game from being good or ok to being truly great. The radio thing is nice, but I believe these other things were more important and ended up being left out.
