I liked the game!
Really liked the visuals, as if I'm really moving my way up a building that's in construction. I also liked that there was a minimap which showed the entire level in real time, really cool! The UI is a bit on the bigger end, which made it get in the way of where you're going. I personally would also liked to have the camera a bit more zoomed out.
Levels weren't too long or too short, solid work!
