Played the lite version. It reminds me of a twist on Pac-Man; you need to collect the nuts found through each level, while robot sentries patrol. Along the way you can collect power-ups (shield, speed boost, emp, etc.) or use the environmental traps against the guards on your tail (using a laser gate to destroy the enemies following you. Control is floating v-stick and there is an arcade mode with a story, as well as a survival mode
One flaw I know most will not like: no auto-rotate.
I didn't see any IAP or ads in the lite version
