So take this all with a grain of salt, as I had to use my incredibly laggy Windows computer
1. I found it a bit frustrating, as it felt as it would often come out of nowhere, and then never stop pursuing you
2. I found that they where relatively easy to figure out, but I found them infuriating to use. I very much disliked that I couldn't look at the mini map and still move at the same time, not to mention that opening your window is something that wasn't really intuitive, and so for a bit I was just quite literally flying blind
3. The only layout change I think it needs is to have the minimap just be part of your movement view, instead of its own panel
4. I had a lot of trouble working through my computer's lag, so I don't think I can answer this accurately
5. It felt a little slow to me, but again, that may just be the lag
6. not applicable
7. I wasn't aware there was an oxygen system, and it isn't clear how much oxygen you have left until you're already dead from running out.
8. No additional comments
