Interesting game, really like how you build up the stakes and intensity, and how you set up the premise well.
Maybe one thing is that it feels like the alien moves too fast initially, I spend a lot of time trying to shake the alien off of my trail, maybe more than I should? It's also difficult to type in the throttle command while you're being chased.
I did really enjoy that the alien just shows up in the corner as you're typing though, it certain adds to the intensity :)
