Hello! Thanks for your feedback!
I may remove the door opening confirmation in future versions.
Sound was always an issue, thank you for making it clear what needs fixing!
The game as it currently is, is very much unfinished and is an incomplete demo. I am planning to expand on it once I have more free time again. I will work mostly alone, though if I get far enough I may add a composer to the team to bring some original music to the game.
I am always looking for more feedback to help improve, so if there is anything else you would like to let me know, go ahead and say it! :)
