Auto shooting and lack of wasd movement are my gripes about controls. As far as the game itself, things get expensive too quickyly. I had to replay the second act a few times to have enough money to upgrade so i could survive the third. also by the third act theres so many enemies on the screen your unable to finish off whole waves, making it very diffiucult to earn cash
Spoilers in this
The Music is incredibly fitting, after I got the first ending, i tried desperately to get others, hoping one would be happy, but I couldnt, so since your screwed anyway, the depressing music makes its only more fitting, the city to "start a new life" is destroyed, the doctor who could answer any questions is dead, and it turns out YOU murdered your family, definitley a chill inducing game to play at 3 am
