I guess it's the whole floaty sky cubes but I was reminded of Kula World when I played this. Nice and chill, a nice relaxing difficulty level and I like that I wasn't really challenged until the very end when you pulled that cheeky can you beat myyyyy score. My only gripe would be that you can't restart levels, so if one does decide to take you up on your challenge.. you gotta do it all in one run. Nice and simple, well presented, nice work :)
