How much can your BRAIN handle? Not Not puzzle game is the ultimate brain-busting challenge based on logic and orientation. Follow the written instructions to swipe your character towards the correct direction (up, down, left or right) and victory. As you reach higher levels in the game, increasingly complex and varied instructions will require use of both your logic and dexterity for you to succeed. And sorry (not really) for any mental inconvenience this may cause :) Two game modes are available: - in the classic mode, discover a new concept on each level! - in the challenge mode, go as far as possible following more and more complex instructions! ***** "Amazing game!" "NotNot is a fun, challenging, and hilarious game. This will cheat your brain many times, so when you finally finish a level, it's super satisfying. It consists of short levels (sometimes) and its very addicting." _by HKapples_ ***** "This game is epic" "This game is epic. The graphics are great, the game is enjoyable and it a brilliant game. It is quite challenging but is still realy fun. You just got to have good reactions." ---------------- _by a notnot reviewer_ ***** "Creative new mind bending game!"
