AGRAV is an iOS game by null2. It's a game about gravity - guide your space ship through 90 levels by creating black holes that influence the ship's trajectory. Black holes are created by (multi-) touch and exert gravity on the player's ship.
Design: Georg Lauteren
Each of the game's 90 levels is a 2D environmental puzzle, confined to a single screen, which you must successfully navigate through skill and strategical thinking.
Challenges for the player include moving Barriers, key and switch puzzles, enemies, various enemies, and planets that exert their own gravity on the player's ship.
AGRAV has been realised in Unity3D and will be released for iOS in Spring 2015.
