You mean the 7z file? Only 2 less known think it is one. It's a false positive. If you are concerned the first 2 are clean: Win3DMaze.7z, Win3DMaze11.7z. You'll mostly miss out on the mod tool, but it can be done manually in the txt files in every version.
You can also check out the source code on GitHub and compile the game if you really want to make sure.
The game uses external txt and png files. I think it might be the reason that some antivirus flagged it.
Another solution is to play it in a virtual machine, the game doesn't need a powerful PC, it can fall back to Directx 9.

Thanks! Did you download the Win3DMaze13 7z file?
In the first version it had an inverted map when you got flipped. I've just checked the controls didn't reverse for me.

Thanks! It might be possible. At least it looks easy, but I'll need to check if it will cause any side effects with low ceilings.

I've only changed the color of medikits.

It's smaller than a rar or zip file and 7zip is free.

This is the final version.

Thanks, I see you also had some trouble with combat encounters. The East Side stop is like that in the original too. The only difference is that you can take much more hits. If you know where to go most encounters can be avoided.
