Somewhere between an overhaul and a content mod, Lightorio is what I'd call a "midhaul".
It will change the entire tech tree and add a ton of items/recipes once fully complete, but it won't remove much and it'll still have your classic factorio feel.
Just a little brighter.

Incompatible with Space Age, (definitely) most other overhauls (untested) and likely many other mods. (definitely untested)
In Lightorio, use the power of light to create science packs. Manufacture the colour-changing compound known as "Chromomixture", expose it to intense light sources and use it to fill glass flasks.
With your science packs, research new ways to create, manipulate and use light - as well as normal, boring machines and recipes for processing items into other items.

This mod was created for the June 2026 Production Jam, a mod jam where modders had to create mods in 8 days.

I would like to thank the following people for helping me with making this mod:
- ArtGeekMagic, for making this mod's graphics for me
- FluidNatalie, for starting the Production jam and before that, the Autocomplete jam
- Many other modders who helped me get this far
- The other modders who participated in this jam
- The factorio modding community as a whole
