Off to make an Impossible Game! Someone else, if anyone's interested, should probably do this because it's gonna take me A LONG TIME 
Yeah, the source isn't going to help you in the slightest. It's written in asm which means there's going to be a lot different, a few problems:
- It's a foreign language to you (unless you know x86 asm or something)
- Asm is structured soooo much differently than Lua
- It's specifically optimized for the structure of asm (in fact, most of the code that draws the sprites is generated at run-time)
- Lastly, it's not all that difficult of a game to make
So, I would recommend you try to make it yourself and find a way to use my level data (that would be a lot of typing (though, I had to do it from a youtube video so...)).
However, if you want the source, it's somewhere on this thread.
