Hound is practically useless other than for finding hidden nodes because it never tells you anything that you haven't already figured out due to already losing lives. Trapped node? You can't know that until you've already hacked the node and lost a few lives! Honeypot? By the time you can scan it, you've already lost a life. If there's a way to scan nodes before you hack them, it's either never explained or doesn't work. Concept and levels are good, but the hacking aspects really drag the game down. Would give four or five stars if I didn't have these issues.
