It's a nice game, sadly my laptop couldn't handle it and only registered a some of the jumps so I always fell after one or two buildings. I watched the playthrough though to listen to the music. I think it must be really nice when it gets into a flow. The changes between the music pieces felt a little rough because they are really different from each other. Maybe putting them into different levels with a slightly different colouring would sort this out. I imagine it to be a lot of fun when it runs smoothly.
