How fun will the game be to play? To be honest, I won't know until it is almost done. Sitting and coding the game makes me oblivious to things that sometimes are obvious and need changing. For example, I made the jump jet key the right ctrl, and as soon as this was shown to a friend, they commented on the bad placement of the jump jet key. I hadn't thought of keyboard ergonomics yet and how key placement can become problems. When the game is close to done, I will release a beta for testing so that I can receive input on what to change gameplay-wise. Until then, there isn't much to put here.
