Is it really a game, or is it ninja stealth spy training that was leaked in app form? With Hexel for Android it may really be hard to tell. You must be fast and you must be stealthy to avoid the barriers that keep moving. Faster and faster they go, and where you stop no one knows. This is a colorful tunnel game that is fast paced, to say the least. You have to maneuver your way through the ever changing barrier walls without hitting one of them.
The game is fun, but for a competitive twist try posting your score to the Swarm leaderboards.This way you can see how your score stands up next to those of players from around the world. Are you ninja spy material when you are compared to other players worldwide, or do you need more training? More training is not a bad thing. It just means you need to play more. If you are number one of course, you still have to play to hold your title.
Be warned however, that if you play for long periods of time and then stand up, the room could start to spin and doors may appear to move. Try not to fall on your face.
