Amusing, but very easy to complete with minimal thinking about the correct path. I wish the background wasn't just water though and was something like a city or countryside instead. The portals don't make a lot of sense with the theming either. Why not something like a tunnel? I liked that mechanics were slowly introduced over time, though it's disappointing that each building was just extra movement. Perhaps they could do more interesting things, like maybe on launches you forward a number of spaces.
