Sonny is definitely NOT a shooting game.
The challenge is in picking the right equipment and skills to kill that nasty boss (Baron Somebody-or-other) on the third level- 30,000 life points!? Sheesh, I'm still trying to figure out how to get past him. I was able to get him down to about 6,000 before he killed Sonny, but I haven't yet figured out how to get past him.
The guy we joined up with for that battle was able to deal out about 3,000 hit points per turn after I cast the Aggressive spell on him (and here I thought I was doing pretty well hitting for about 400 points per turn), but my other sidekick got killed pretty quickly, and once the boss turned his attention to that new guy, well... let's just say that we didn't last long after that!
Awesome game, very addictive!
