Hi!
I am amazed that you managed to past those four last guys! I think I needed to use more time balancing the difficulty...
Thank you for playing and commenting!
The difficulty was fine once you get the hang of the enemies and where everyone is.
The last four certainly were a challenge but most of the trouble I had was getting back to them after I died having to replay the entire level again and dying whenever I would break my pattern.
Still was a great game and worth taking further if you choose to.
