How can I run this program?

I've also found some pretty serious memory leak issues. I'm using the VisualStudio version of the software and I'm building it myself, I just added the glew-2.1.0. I've found that each time a level is loaded, it increases the amount of RAM used, so I think the issue might be somewhere around the loading level system.

Here's the RAM usage as shown from the VisualStudio Diagnostic Tool
First level: 388 MB
2nd: 565 MB
3rd: 794 MB
4th: 1 GB
5th: 1,2 GB
6th: 1,5 GB
7th: 2 GB

This is what happens if you load the levels one after the other. During the level the RAM usage stays perfectly constant, and only spikes on the new level. If you load a level once again after having already played it, it still increases the RAM usage

Yeah, I noticed that too. He (or someone) needs to make the game unload the previous level when loading a new one.

If you load a level once again after having already played it, it still increases the RAM usage

That sounds like it's a straight up case of not freeing resources that should be freed. Maybe take a look with Valgrind?

Hey, I think I narrowed down the memory leak to the mesh class, don't know if this helps anyone or if anyone else is trying to fix this

@Chaosminecraft When you download the repository, there's some files directly in the ZIP, and most of the stuff is in the folder NonEuclidean. Among that bunch, there's also a NonEuclidean.exe, simply launch that.
Assuming you're on Windows. On Linux you'll have to launch it with Wine, and I think there was something similar to Wine for MacOS as well.

@ehx-v1 thanks, I did not explore the folders yet, I'll look if I still have that or I download it again.
Cheers
