It was engaging, atmospheric and also uneasy at times, but I wasn't able to complete it as I crashed into the alien plants around the third signal location and couldn't get unstuck (completely my fault). 

For the first 30 minutes I did not understand that orienting toward the target involved moving the radar blip to the middle of the screen, and instead tried to move it to the top middle, as I was under the impression that it was top-down (again, completely my fault). 

I felt like my FPS dropped as I spent more time playing, but I'm not actually sure if that was the case.

Other than that, it was really cool! I might return in the future to try and see the ending.
