Easy to play but hard to master and so it's nice :) Although I think the game could benefit from couple things like some indicator in which direction you currently moves. If you try to stay in line (horizontally) you have to trigger the space key. Then if you release the space key it takes some time (because of the slow acceleration) till you realize in which direction you'll move. This makes it very hard to avoid obstacles, especially if there not enough space between them. The other thing was, that the item spawns sometimes much to close to the obstacles and some times they overlap. Thus it's not possible to collect them and avoid the fox.
But here is some potential :) Keep it up!
