This is actually a weird little level. It takes a total of one minute to do the entire level, so I will rule this as a "casual level" since I can't take this level seriously.
As a few notes though:
-It would have been cool to have every turtle be the same color as the mushroom it was on: IMO
-Mushrooms can't just spawn on a mushroom, they form from a central stem a majority of the time.
-If you have a stem, make it lead to a mushroom. Using these as BGOs feels incredibly weird and disconnected
-I highly recommend making the level longer by a few more minutes and incorporate multiple sections.
But that is all I have for the notes. I won't give this an honest review unless specifically requested. As of now, I will consider this as a "Casual Level" due to its laid-back nature.
