Thank you for yet another strikingly generic post. I love reading over and over again that people think it is illogical and stupid without explaining why.
I think you are right however, simplifying the keys is a terrible idea. I will back this up and suggest that we make the keys as complex as we are able to in order to make this game more fun. From here on, let's have it so that in order to shoot one must insert the key commands "Up, Down, Up, Down, a, b, a, b, select, start." In order to active one's jump jets, we should have to type "SuperKalaFrajalisticExpeealaHolyCrapThisIsComplicatedAdocious". Of course you would type this in AFTER hitting the jump button and in the 2 second window before your body returns to the ground. More key bindings please... That is all.
