I completely agree with you that sleep is good. I to had a lot of problems finishing my little game.
By the way, this reverse R-type is fun, i am just puzzled on all the different options and things i can do. Everywhere i click something new happens and i am never sure on how good i was. Also, no matter how many times i tried, i wasn't able to collect any scraps, i will try again because the idea is really interesting, just a bit chaotic, in my limited experience.
