Yeah this game was actually meant to improve my pixel art capabilities since all of my games before had really bad or overly simplistic sprites so I wasn't able to properly flesh out and polish the gameplay mechanics as much as I could with my previous games. I am so happy you liked the atmosphere since that was my main focus for this specific game and this was my first game where how the game looks was the main priority. Also yeah the game is supposed to loop with you falling back to the entrance at the last level I definitely could have made that more clear as the intention rather than a bug. I am really happy you enjoyed the game and I will try to fix the issues you had in future updates.
Thank you for the kind words and constructive criticism I will use this to improve my future games.
