Honestly really fun, reminds me of other games I've wasted a lot of time on like Flappy Bird and Doodle Jump. Two suggestions:
1) Is it possible to make a multiplayer mode? It'd be awesome if you could try to beat a friend through the barriers, especially if you could bump them into the barrier by hitting them
2) Could the track be procedurally generated? A lot of games like this are basically unlimited because the obstacles are triggered by some function that more or less runs off of a random number generator and you get a higher score the longer you run. You could probably get people really hooked if they could get more playtime and brag about their high score to friends.
