Loving the music, and the art is v nice :)
A few critiques-- wish there was a "next level button instead of going back to level select each time, and also maybe an indication that I'd beaten the level. Also, once I paint over a turn pad or jump pad I couldn't see where they were.
I also encountered just one bug where I escaped the map on the fifth level of the second world using the jump pads. (I also still haven't figured out how to beat that level because of that one spot three down all the way to the right..)\
But it was all really enjoyable!
