I think I'm missing some kind of tech, a lot of later levels seem to expect me to generate force from nothing
Hey Goose, really good luck if you come back to the game! All the levels are solvable, no extra force is needed. If you're having a hard time with the final 10 'red' levels, I tried to make them very tough, again good luck!
As a little tip, if you don't have enough energy at the end of a level you must have lost it somewhere
