Sorry, but I think you need more visual ques on where I need to go. Also some indication of how much longer I have until I reach my destination. It would be interesting to know wow can I determine an optimal route.
The gravity arrow was confusing too. It feels like it's telling me where to go. I'm not even sure what those orange balls were. They just went out of sight after going too fast or something.
I think you have something, I just think you need to present it in a way so that it's easier to pick up and know what I'm getting myself into. I'm sorry if this criticism is harsh, but I stopped playing this game with a lot of frustration.
