(accepted) Pointless Filler Level

I made this level to fill an empty space. I've actually had the idea for this level for a while, but only just now got around to making it. It's short and a bit slow to start, but I think it's challenging enough to fit World 5 or 7.

This was a very enjoyable level. Short and sweet. I especially liked that the timing with the music at the end. This level would work nicely as a secret level.
One small nitpicky thing though: When the lava rises through the pipes, the top part goes over the pipe while the bottom part goes under it. I'm not exactly sure how to fix this, but it would be nice if you can.

Keep up the good work!
