First of all thanks you for the detailed criticism of Episode 3.
As for the noise propagation. I did tweak it slightly throughout development but i believe it is mostly faulty level design
I did not plan out the encounters accordingly and wish to avoid that in the future.
There was not enough playtesting on my part.
I removed the megashotgun because it just kind of didn't work out.
As for the final boss it is exactly what i wanted, a do or die struggle at the end of the game.
I do understand that it breaks the flow of the game somewhat.
Again thank you for playing my game to completion and i do take all your points into consideration.
Ill try to fix some of the issues in future updates after extensive playtesting.
Ill look forward to your lets play of the last episode.
