Yes the rest of the level is semi-randomly generated after the first 4 platforms, but from a lot of play testing I made sure every platform is crossable (even the super long gaps) if you are good at conserving your ammo and arm length (you can shoot downwards to push yourself upwards with the recoil, your gun hand is also your main movement tool too. Your grabbing arm gets shorter the more you climb with it unless you find uncommon hand pickups!)
