You have to learn how to win most of these challenges by dying 5 times or guessing correctly. I mean seriously, how do you know whether you need full power or minimum power to blow something up without reading a manual that tells you how powerful the gun is?
If anyone would like to know about the switch puzzle: for the door to open, the circle means that switch must be to the right, the horizontal line means it can be either left or right, and the vertical line means it must be to the left.
I would dislike this game less if it had an effective way to restore HP and maps to explain the oddball way of moving around. Also, some more quests and less grinding would be great.
You'd think a guy would be bleeding to death and trying to crawl to the hospital after crashing through like 10 windows and falling at least 50 feet. :P
