This mod isn't really doing anything even after setting everything up as instructed. It just starts normal seablock.

It doesn't even research the recursion research.

My mistake - I made it quick and didnt give it proper testing to notice that it was only working if you unzip the mod. I fixed that up and added a few more changes to make the gameplay a bit better.
The updated version (1.1.2) should work without any issues - I tested it out on a fresh factorio install just in case.
To start just install the mod (plus any QoL you wish) and go to new game -> Factorissimo - Seablock / Basic (under Mod Scenarios) instead of starting it as freeplay.
