Flop Rocket is a well polished, engaging one-touch adventure that sees you bobbing through a cave in an attempt to break the surly bonds of gravity and soar off into space.
A slider on the left of the screen lets you position the angle of your rocket, and tapping on the right fires your booster.
You're given a series of missions to complete, and there are coins to nab as you fly. You can use these to buy upgrades to get that bit closer to the black beyond.
There's an interesting free to play system here as well, that gives you lots to play with, and more if you pay.
This is a surprisingly compelling, often funny little slice of mobile fun, and it'll fill a few minutes quite nicely.
