The simple graphics were fun. I wish it have some juiciness to it. I don't think I should have had to made it to the top platform for it to continue scrolling up.
The platforms are suppose to transition through random speeds (including 0), but maybe you found a bug 🐛 The code's full of 'em haha. Also, yes and yes to the juiciness. I would've loved to make the dark place larger and use the colorful fires in more places.
