-Try making a pick up where you can restore lives (I only played up to level two though)

-You know all the green orbs travel in one direction right? So if I stayed in the bottom right corner platform, I was immune to everything.

-When the player spawns in level two, they just drown in this endless void of green orbs. Try clearing the screen of the orbs from level one and re-spawning new orbs from the sky (not from the platforms) that way the player has time to position themselves before dying.

Otherwise, fun cute game!

Bcause the green balls only move in one direction, its pretty easy to avoid them.
And it become very laggy in the end.
But in the end, your Idea is simple but good ;)
