In caves level 9, I noticed a tearing glitch when moving the character near that particular structure:

Here is another screenshot with higher gamma level:

I also noticed that if I pause the game and then resume, the yellowish colour from the menu text remained and "replicated itself" in the direction I was moving the character on, leaving yellow spots on that map element.
Here is the save game, I left the character exactly to the left of that glitchy thing :)

This is issue known af Hall of Mirrors:

There are a few of them known in town even for the original game, but I haven't seen them this ovious or in the caves. Maybe @galaxyhaxz knows if this is expected or what might be the issue.
This is a "feature" from the original game. I have already experienced it in the distant past.
Ok, then no issues with this anymore. Keep the originality of the game, right? 馃檪
Btw, thank you very much for your entire work on this project. I am looking forward to finishing the game with all the classes on my Linux machine. Will report everything I find itchy here.
