Hi, glad you enjoyed the game!
To clarify, the "you are the enemy" theme is from the fact that the clones (the red cat enemies) copy your movements from the previous waves, including your attacks, and therefore your own bullets become a weapon against you.
And thanks for the feedback! I do agree with the points you brought up, which will absolutely be taken into account if me and the rest of the team work on the game further.
