The concept is fun at first and the incredible graphics make the game seem very professionally made, however it feels like it is too lacking of content. The game itself is a very good time waster, however the concept gets boring. What I suggest is to maybe add a 3D mode where you have to jump on a 2 dimensional surface rather than a 1 dimensional line. And maybe have enemies that are trying to get you and kill you as well as power ups to help defeat them or even be immune to the spikes for a little bit.
