Although the map does indeed look like it would be fun to play, the rainbow theme has been done so many times it has sort of gotten to the point of no return. The map is essentially a bunch of color glass blocks, placed with no real reason behind them except to create a path. There is a blocky main art piece which does not really add much to it. I would suggest adding more detail, and just more stuff in general. Though I would highly suggest maybe switching themes, as this theme has been done too much as it is. I am not staff, this is not a final decision, but I would deny this.
Thank you for your time reading my comment.
