On the line Hack 1.5.3 + Redeem Codes

This game is great and so addicting!!! Perfect for long plane rides or any other time that you need to keep occupied. Love this game.

I'll start off with telling you it's a very good game. It's the perfect ballance between hard and easy. All it needs are a few tweaks. First, after around 160 it starts to lag every now and then. The lines are also a bit blocky and could be smoothed out, but that's just a personal opinion. But it is very fun. Definately buy it. I also like that the achievements are wonders of the world. That's pretty cool

I just bought this game on the first of May 2014 and it's been a pretty good experience. I like the realism of how much one cm really is in comparison to how fast the game moves. The music isn't half bad either. My only complaint is that this game was designed for a stylus. With one, you get much more precision and control, without one, your fingers might accidentally touch the edges, even of you know your finger was straight on the line (due to the fact your fingers are a big size for this game, even if you have small fingers like me), I don't think the developers will be able to fix the sensitivity of the edges too much, without making the game too easy, but I do hope they make the screen size of the game bigger, and maybe adjustable, for the iPhone (I own a 5s). And maybe add more measurements besides centimeters. Overall good game with needed minor improvements. 4/5

Needs fixing. I'm #20 at this game so listen to me. I died at 700 cm because the obstacle wasn't moving fast enough for me to get through. It was the narrow path with the sliders. I had no opportunity to get past the sliders because their speed does not increase with the speed of the course. It was actually impossible for me to have gotten past there. Probably the reason no one has beaten 1000 cm thus far. The moving things should increase speed with the course, or at least just those. I haven't had much of a problem with the other moving obstacles but what I said should actually be fixed so do that.

This casual game is a 4 star game (primarily because no other dev has come to make the same type of game at better quality), it is NOT unchallenging and IS worth $ 0.99 contrary to what one reviewer comments. Why 3 stars, then?As noted by others, this is not a good iPad game for the current os in that it has NOT been reprogrammed to run optimally with the beautiful retina capabilities. The graphics are downright ugly in a lot of the UI.

However, don't let that deter you if you have the dollar to waste on a fun time-waster... I imagine the developers wouldn't let such an awful UI permeate an otherwise decent game for long before they update.

I love this game. Absolutely love it! I downloaded it just to try and ended up keeping it because it's so simple yet so brilliantly fun. My only complaint is that when you play on the extreme game mode and start to go really fast it's impossible to win on one of the obstacles. (The one that's a straight line with two bars that come across your path). The bars are too slow for the gameplay and you always lose. If this is fixed then I give it 5 stars!

Just when you think this game is going to be easy, it throws twists and surprises at you. It's challenging but not so much it becomes frustrating. It's kind of an endless runner where your finger is the runner. Lots of fun, and addicting. It has leaderboards to beat, and plenty of Achievements. The game is polished and well done with attractive minimalistic graphics. I recommend this highly!

I'd give it 3 stars but I've noticed (and video recorded, to make sure I wasn't crazy) that you go out of the line when your finger never really touches the edge. I thought maybe it was an optical illusion because of the speed but I recorded in slo mo my game and sure enough my finger never touched the edge of the boundary to be out of the line. So please fix it so it's more accurate.
Also, when I tap for leaderboard it shows, No Items, and doesn't go to leaderboard-wants me to do rate the game. Please fix this as well, because obviously if your reading this, you know I rated it.

First i have to say that there is a problem with the pattern with ball that goes around because when its going around theres a little space and in the zig zag pattern you dont even have to move your finger and please fix it and please put more patterns with balls please if you read this thank you and you games is the best on the app store

I was really amazed when I got this app. It feels so fluid! However, I do wish there were more obstacles. :) you unlock them as you go (I'm pretty sure). I just got this, so I haven't unlocked that many. Also, I love how the objectives relate to the height of real world objects (travel 2400 cm w/ your finger to reach the height of the Chichen Itza. All in all, a great game for 1 dollar.
