Can't hate it
This was a pretty hard game for me because I didn't know how to get strong enough to eat a human. I will give you credit for making it so that you keep all your blood as you go along. I also have to give you tons of credit for actually having a walkthrough in this. I will simply not be able to progress through this game without it. I thought the graphics were decent, especially with how the piranha swam. I know all I need to about piranhas from "Piranha 3-D".
As a note, that's probably the most disgusting movie I've ever seen. It's interesting to have those little holes you can teleport anywhere with. The music is also good and it fits the tone. I do wish that you would make it easier to kill the guys as I keep clicking on them and nothing's happening! At least it's fun to wreck their boats.
