If in addition to launching your whatever and trying to go as far as possible, if you also had to fire at enemies and defend yourself while in flight.
I mean, one of the main things people complain about launcher games is that they don't have enough upgrades and have all been done before, right? So why not make one that has the added twist of having to keep yourself alive throughout your flight as well (if nothing else you would at a minimum have two new things to upgrade with weapons and armor)? Naturally, enemy threats would have to increase in power the further you go.
It also would give you something to do while going the distance, as most launcher games give you little to do while you wait for your hamster, kid, penguin, and so forth to land.
