well for starters when the person jumps onto a platform it immediately snaps camera to his position. This may feel a bit clunky so there are a few solutions. 1. wait a few seconds before making camera lock back onto him although may make game less fast in terms of gameplay 2. smoothly lerp camera into the player this will seem smooth but might also undermine the low res graphics. Do the same thing for when u die and also add a message or effect indicating that you have died.
