WOW! This was a lot of fun. I actually got the crown on my first try as a "Weekend Adventurer".
I did want to ask if you could make the blob wander around the tunnels in search of the player. If I can get away from the blob it will just sit there. I think in the original game the blob did wander about and then would speed up slightly if you caught its attention.
Finally, you should think about expanding on this great remake. Perhaps add more monster types with some such as werewolves requiring silver arrows to kill. I better not start as I can come up with dozens of ideas and make this post pages worth of text. LOL! Anyhow, I'd love to see you expand on the original game and make this a Super Pro Murky Mountains.
Great job on this remake.
