LÖVE

I did a search for [LÖVE ubuntu liblove love dbg] and got nothing but the Love page it's installed on. What the heck is the difference between liblove and love, and what's a dbg? There's no mention in the wiki either.

liblove is a requisite for love. You need both.

In general, a dbg package contains debug symbols; useful if you experience crashes and want to provide backtraces to the developers, or if you want to debug the program itself (LÖVE in this case). Otherwise you can ignore it.
