Got all three endings, found a lot of radios but didn't count them. Probably found all of them though.
The prophet area was specially pretty, hadn't seen that tileset before. The only part that I felt was a bit more challenging to me was when I had to use the umbrella and avoid those scrolling spiky squares.
Overall it was a nice level, the only thing I didn't like was the excessive amount of save points. But there's a good chance that's just my problem, since a lot of people seem to hate the way I usually distribute them.
