I disagree with "ruining", I've resorted to looking up some hints; mind you, in hindsight I would've figured it out myself if I spent a bit more time on it.
Eh, I think that game definitely needed a bit more play-testing polishing. More than once I got stuck and had to look up a hint. Only to discover that I actually had attempted the correct solution, but the mechanics were so clunky I was mislead into believing I was doing something stupid.
