==============================

- any blue particles represent something that is interactive, like a Switch or a Power-Up

- any red particles represent a trap that will restart the level if you hit them!

- if any echo particles hit a moving platform, they will stick to it for a limited amount of time, showing you how big and how fast it is going!
