Flop Rocket, by Butterscotch Shenanigans, is a rage-inducing physics game where you try desperately to pilot your spaceship through a a cave filled with spaceducks and enormous rockworms.
With each failure you'll earn money that will allow you to upgrade your pitiful ship into something a bit more space worthy. Flop Rocket also allows you to play auto-generated missions based on your skill level. It uses touch wheel controls that let you flip your rocket around quickly, but you can opt for tap controls instead.
