The gameplay has is own style, the fact the controls aren't "friendly" gives this game the right amount of challenge.
Audio and visuals give a gloomy atmoshpere which I like.
I didn't have the patience to kill enemies, even because I think it's too slow to kill them (aiming system, fire rate) so I just "speed run 'my' way through the hail of alien bullets" as you mentioned in the description.
All on all a solid entry, with a great initial cutscene. Great job!
P.S. Is that a loading screen between map transitions? I think in a game like that the load time is just too short, maybe you can force it to be longer?
