Great early version, maestro.
Love your games truly, hope you want some feedback:
The synergies are working well, but I had some trouble remembering, which structre buffed what exactly. Something like colorcoding the buildings (bio, ele, mag/sub, elix) or maybe highlighting affected buildings when hovering production came to mind.
Second UI feedback would be the tooltips sometimes taking almost all the space of the buy button, making it barely clickable. Chrome browser.
Idea: button to toggle view globally for upgrades/calc/buffs etc, right now it can be a bit clunky to compare multiple buildings stats while you want to keep upgrading, since the menu remembers you last choice individually.
All the best and thank you.
