Hey all, this is the dev, thanks for comments.
This was my first game so there some design flaws and bugs, I think I learned a lot for the second version. Jaymon, regenerators are supposed to be hard, and you have to hit them just when they enter the field, but yeah, maybe they are too hard. Shinosuke, maybe you have to many exits on a generator, a generator with more cables comming out from it gives less energy.
Thanks again
