Current status:-
Not yet considered "stable", but remaining issues are very minor- Known to have some minor rendering bugs (generally of the kind "something is drawn in front of something it should be drawn behind")
- No dedicated editor yet, but can load custom levels made for DOS L3D

https://bitbucket.org/namida42/loap/If you are looking for the source of a specific release, look for the branch "release/demo/[version]" eg "release/demo/0.0.25.0" for 0.0.25.0.
You do not need a copy of DOS Lemmings 3D in order to play this; all needed files are included to play the official Lemmings 3D levels (including Winterland). My level pack,
Lemmings Plus 3D, is also available for Loap.
The binary is only available for Windows at this stage. It has been confirmed that Loap can be compiled from source for Linux, and it likely can for Mac too. I intend to make Linux (but not Mac) binaries once Loap reaches a stable or maybe even just RC version. You can edit resolution settings, including fullscreen mode, in "Loap.ini" (which will be created after the first time you run Loap V0.0.13.0 or higher).
To see (or configure) the hotkeys, go to the Options menu then click Edit Hotkeys. You can also reset them to default here. Some hotkey functions (eg. select skill) are not assigned by default but can be configured.

Custom levels made using L3DEdit can be added to Loap by placing them in a subfolder of "data/levels", which may in turn contain subfolders for ranks. Rank folders are sorted alphabetically in-game; if a rank folder name begins with a number and then a space, the number will not be displayed in game (this can be used to order ranks that aren't in alphabetical order). Level files are likewise sorted within a rank by alphabetical order of file names.
