i really like this!!! the simple glowy aesthetic is nice, and i really liked the trickledown feature of making upgrades cheaper for the previous buildings, it feels kinda fresh when you're playing a ton of incrementals right after another like i have been doing XD
i know this isn't like, a recent demo but if you do come back to this my suggestion would to be able to move the flux tiles, even if it has a cost, the place that they were at messed up the symmetry i had going :'D
