Title: Gravity Swap
Gravity Swap is a small Arcade game for Android. It was made over the course of 3-4 days as a way to better understand the processes of publishing on mobile. the game itself is very simple, you tap on the screen to change the direction of gravity (up or down) and avoid the red spikes. In addition there are power ups that change the speed of the game, give you immunity or just give extra points.
Give it a go: (not currently available due to the changes in the play-stores terms!)
