I found myself enjoying this. It may not have been that well detailed, but it was certainly quite fun. Wow, you added medals fast. I assume a 30 is when you get the medal. I got close at 28. I didn't even know how to collect those things at first.
I admit I was annoyed at how the dialogue was repeated. I never had problems with air. It was pretty easy to just avoid stuff if you wanted to. At that fast a rate, you can get lucky (or unlucky, depending on your point of view). It does a lot with its simplicity.
