A fork of Factorissimo 2 focused on improving performance by implementing several 1.1 features. Can improve performance by 10X or higher. Also fixes several bugs from the original version.
Not sure if this was intentional or not, but I noticed that on every new game, if I haven't yet researched interior lighting, and I somehow place a solar panel on nauvis, the interior lighting technology ends up being flagged as researched.
With cross-surface poles, having one surface at nighttime "corrupts" all other surfaces, causing solar panels to break. This is a vanilla bug but the devs don't plan on fixing it. https://forums.factorio.com/viewtopic.php?f=48&t=96830
The technology is researched because if the player somehow gets solar panels early, they need to be usable.
