I’ve never seen the concept of reducing upgrade costs to 0 like this, it’s a really novel and fun concept!
The only thing that confused me briefly was the fact that the Light Framers only upgrade neighbouring buildings, while the other reducing buildings act globally. I thought that the Flux Crystallizers had to be next to the Light Framers for most of my playthrough. Could be useful to highlight “neighbouring” and “all” in the descriptions so it’s more obvious, and probably specify that the Processor applies to all target buildings too.
Really fun little game, the third one I’ve played from this creator so far. I’ve really been enjoying these shorter incremental games that are decidedly not idle games and have a clearly defined ending, it feels like my time is being respected.
