As Force Master and Astromancer I use ss to get behind one of those monkeys so that I am on green part of platform. In that way you can easily avoid red attack and all monkeys suddenly get in front of you. Only thing that remains is to block in right time. You just need to know how far do you ss, so you don't ss into water. Probably you only need to get on the green edge of platform, but I just want to be sure that every monkey is as much in front of me as possible :D
