The game was interesting, especially the probability factor that you had to account for.
Oh and for the folks having a hard time, it helps if you start by maxing out your main movement skills (left, right, jump, then duck) before adding point into the last two (fire, then jumpjets). Also, don't try to rush through things like it was a race. For the earlier parts (after left and right are maxed out) jump up first (that way you don't glitch up and fall to your death) then move while you are going up.) When you reach fights that let you jump as well as crouch, jump more to dodge and hold down the fire button while fallind back down.
Trust me on this, once your main movement skills are full, the game becomes easier.
