Thanks for making this project, it is really nice. I built and ran it on Linux. I even made a PKGBUILD so it is easily installable on Arch Linux https://aur.archlinux.org/packages/loap-git While doing this I had to do a small patch where I put the settings, progress and replays in the proper user directories. I think you should patch the source to do this too. Something I couldn't figure out is if it is possible to pan and rotate using the mouse? It did not work for me at least but the code seems to suggest it should be possible. Some of the background graphics are horribly low quality so it would be nice if we could replace them with higher resolution versions if possible. I'm also wondering if it would be possible to replace some of the sprites with proper 3d models or to make the lemmings voxel based like in voxel doom if you are familiar with that project. Anyhow, great work
