Space Bump is a simple arcade game where you have to take charge of driving a UFO around a city while absorbing everything you come across. You see the whole level in 3D, which makes it much easier to plan your moves.
The controls in Space Bump are quite simple: you just have to tap left or right onscreen to move your flying saucer. On the other hand, there's also the option to raise or lower your altitude as you try to calculate the buildings and structures to avoid crashing into.
Throughout each level there are several animals and other beings that you can absorb with your UFO energy. As you bring up items into your ship your score will increase.
Space Bump inspires you to keep playing new rounds and trying to beat your own score. That's the only way you'll manage to send all the living things that inhabit your planet into outer space. Finally, do note that you can use the rewards you win to unlock new skins for your flying saucer.
