I think I've decided to still use the mouse wheel but change it to just scrolling in one direction instead of going back and forth. Then, instead of pressing E on a droplet, you just have to scroll the mouse wheel once you are near the droplet. I was worried this would simplify things too much, but since you have to still charge the battery, bring it to the battery pad, and wait for the charge to drain, it still feels as I believe an incremental/automation game should feel.I tried making it so that you could just be present in the droplet, but that introduced some wild and unexpected bugs that didn't seem worth it to me as a developer to fix haha... Thank you for the suggestion though!!
