Overall, it was a really good game with a couple of issues personally.
The game gives you an E-11 halfway through and then takes it away only to give it right back 10 seconds later for a room-clearing section for no reason.
The melee attack is worthless and will more than likely get you killed.
And without spoiling anything, the ending cutscene is just a slap in the face for no reason considering what you go through 15 seconds prior.
