Thank you! Yeah, the spikes can be used to exploit a bit, but I felt that it was okay if I made it too hard to compensate for the balancing:P. The trick is to only use a fish when you're 1 or 2 hits from dying, or spikes of course!
This is the technique I used, made it down to one hit left on myself but made it through on the first try. I liked the simple movement technique which could have gotten bogged down in the 3d view, it works really well.
