I got this in the Steam sale. I had a great time with my first run, honestly. I picked the assault rifle as my weapon, and had a lot of fun mowing down enemies for two levels before I died.
I wish I could save between levels and continue from there, instead of having to start over. Gah. I don’t know if I have it in me to keep playing a first person shooter from the beginning every time I die. It just seems like a stupid concept.
