Well, I did not beat my high score or achievement level 33 (my highest). I did make it to level 22 however. What a lovely, frantic game to play. Completed two bonus stages, almost got to a 3rd but didn't make it... :-/
Alright! It was tough as I had a hunter alien on my heels the whole time, but I was able to reach Nicole, who was attached to the Marker. I defeated her (eventually) and made my escape with Ellie. What a cool game. Final boss and game ending! Great stream!
