I have played the tutorial and the sewer level for now. The movement is really fun, unlike the other guy I found strafing to be quite useful. Graphics work, music is decent. Some parts of the sewer-levels feels a bit unnecessarily crowded with the amount of enemies. I did quite often accidentally trigger the Bomba ability. I am not sure what a perfect button-setup would look like but that might be something you would want to take into consideration. Tutorial-boss is a bit hard as first real encounter, movement and everything is good, I would just lessen the amount of stages for the last part where it is stuck in the center.
Putting this on the play more list. I will be humanity's shield.
