Played the first level. It's not that great. Most of the difficulty is from the absurdly fast movement of the player character and general lack of cover, so you often end up trying to circle strafe in a room full of enemies that match your speed with their aim. Prepare to regularly have to see through a giant red low health aura covering 60% of the screen.
There's a sound issue that bugs the crap out of me too. When low health, you hear a heartbeat, but the noises from walking around actually mute it out, meaning those two sounds cannot be playing at the same time. WTAF
