But if they add 3D features, they can't call it Löve2D anymore. Perhaps Löve2.5D will be a better name then. Or Löve2.718281828459045D for that matter.
Sorry

Well, I'm currently rewriting the logic to
1) Extract the coordinates of the wall (at love.load() time)
2) Cull the walls outside of the field of view
3) Use linear algebra to get the distance rather than the current iterative process.
It will hopefully be faster still (and make the tracing speed independent of the field depth, but dependent on the number of walls).
Improvements to the player's moves logic are of course welcome :-)
Regarding the arbitrary quad deformations, they could be useful in other 2D contexts too.

Well, the SNES had 3D games, but it wasn't a 3D system. I don't think anyone would complain if Löve suddenly had simple 3D features if it was still primarily a 2D engine.

Hmm. Maybe they could just shorten it to Löve.

Well, I never refer to it as Löve2D anyway. Why limit yourself from the start when the future is uncertain? Who knows what they'll be able to do in 3 years? 5 years? 10 years? 100 years? Because we all know Löve will last that long.

I'm still mildly curious as to why they decided to call it Löve to begin with. Heh. Though it's probably in a FAQ somewhere that I didn't bother to read.

We can't really say that we're making love, now can we? Plus, adding an umlaut makes anything awesome, just look at Motörhead.

Neat stuff, though there is a slight element of futility in doing this all in pure Lua with Löve
. Since you're intent on doing this, have you though yet about placing billboards and mobile sprites in the scenery?
It looks like you'd have to draw them in the right order. For example, imagine a monster in the cavern being half hidden by a corner, but in front of a wall further away. You'd have to draw the distant wall first, then the monster sprite, and then the nearer wall that obscures half of the monster sprite to get it to look right. Or alternatively draw the monster only where the rays hit it, but in any case the rays will have to continue further than the monster to give you the background wall (I'm assuming the sprite is partly transparent of course).

Hate to break the fun here, but AFAIK it was always LÖVE. love2d.org is just the domain name -- one might imagine love.org was already taken.
