i know you can get past them...
but the trees on the cliffs are a real pain and take a bit of fun out of the game. especially when youve just started playing the game and are not skilled enough at it to hit the trees. id suggest, if anything, taking the ability away for them to spawn so close, and allow them to move closer to the edge as you run farther. it takes some of the fun out when you allow one of the harder obstacles to move past spawn so close to the start. otherwise, the music was fitting and nice and the art beautiful, it has been a concept done many times before though so you lose a bit in originality. not much though because you add some new twists to make it interesting. keep up the good work, just take into accountability the learning curve of most players, i dont know about anyone else, but it took my a while to actually start hitting the trees effectively. that still doesnt mean you didnt do a great job. keep it up.
