I somehow ended up with two death-eaters who were just draining each other at equal rates... the timer ran out but didn't end the match so I had to surrender even though mine had higher health :(
Only one complaint: I started playing this on campus while logged in to Kong and could continue from another campus PC if I logged in, but as soon as I got home and logged into Kongregate my save disappeared. To do with IP maybe?
The concept is great, but this type of game requires a minimum of problem solving along with co-operation, which becomes near-impossible to achieve with high numbers of players. The result: a incredibly stupid mass suicide.
