This should be on iPhone or some other mobile phone
I would if I could! You need a Macintosh to make games for iOS. Unfortunately the staggering $1.52 that I've made in ad-revenue (which I can't collect anyways) isn't enough to pay for one.

This is like Canabalt or Robot Unicorn or both
I hadn't played Robot Unicorn until I heard about it here, but I had played Canabalt. I found Canabalt kind of annoying because if you actually think about it the best strategy is to go as slow as possible so you can avoid the hazards. Also, in Canabalt the only ending (unless there's one I never managed to get) is that you mess up and die. You basically grind it out for as long as you can and then you lose. It's fun despite that but ultimately when the game ends it rarely feels like you deserved to lose.
I wanted Edgey McEdgerson to be about going as fast as you possibly can, and to be about succeeding instead of failing. That's why the only thing you can interact with is the hedges, and the only thing that can negatively affect you is gravity. Even if you fall the game will put a hedge directly under you and try to bring you back up to where you were. I also didn't want it to be a "who can play the longest" contest, which is where the time limit came from. This creates a situation where the best high scores come from good strategy and not the amount of time you can invest.
I think the reason the game is fun despite being so simple is that it still has the "I can do better" aspect of Canabalt and Robot Unicorn, but it's not as punishing. Plus the ending is (hopefully) hilarious and unexpected.
