What Hacker News says

2 sources
My libraries were originally made in Lua in order for me to better work with and learn the LÖVE framework. * inspect.lua [1] is the most popular one. It transforms any Lua value (including deeply nested tables) into human-readable strings. It is very useful for debugging all kinds of Lua projects, not just games. It is a partial reason why I got my current web dev job at Kong. * middleclass [2] is somewhat popular amongst people coming into Lua from OOP languages. I don't use it myself anymore and consider it a bit of a "clutch". Still, it has helped a lot of people. * bump.lua [3] is a box-based collision detection and resolution library. The later part has some known bugs I never figured out. Still has been used by some people to do some fun stuff. * gamera.lua [4] is a minimalist camera-system for LÖVE. * anim8 [5] is an animation libr

ary for LÖVE There's many other projects on my github profile. I must warn you that they are all in several degrees of disrepair, I pretty much abandoned all of my open source efforts when my first child was born. Ran out of free time and energy. These days, when I want to scratch my game-making itch, I fire up PICO-8, an even more minimalistic gamedev environment than LÖVE. I find the limitations it imposes refreshing. It also means that I cannot use most of my old libraries. Which is fine.

In Doing what you love when the money won’t follow
For developing 2D games, I've found the combination of Love2D [0], Bump.lau [1], anim8 [2], and Gamera [3] to be extremely productive for me. This is a Lua game engine with additional libraries for collision detection, animation, and moveable/zoomable camera. I'm an embedded C++ programmer by day so I've almost certainly done many of the things on the OP's list. It wasn't until I set C++ aside after 15 years or so and gave Lua a chance that I finally started making real headway on my Secret Agent Sam remake.
