So, as a couple hints:
1) I can confirm, the game is possible and not broken.
2)Have you played project Kat? If not, that game is something of a tutorial for this one.
3) there is ALWAYS an alternative way of doing things.
Hence, for example, the fuse puzzle is perfectly possible if you are willing to pull out a few of the fuses from below (you don't NEED everything powered).
4) Getting behind the bars in the lab is useful, but not needed. (Also, there is no valve there).
There are guides to get you through elsewhere in this comments section if you need them, but for now I'd encourage you to try without. Good luck!
