I found it to be pretty easy but it feels like the introductory levels to a full game so they should be pretty easy. Since there is supposed to be more eventually, this would be about right. Edit: Not applicable, haven't finished.

But the teaching graphics make no sense to me. I accidently figured out I could grab a bomb and use it to break the purple wall. Then in level 18, I'm stuck. I cannot at all figure out what the graphics mean and so I can't complete this. Edit: Finally figured it out though the graphics still make no sense.

Definitely enjoying this. If the full version ever comes out, I'll probably buy it!

Edit: I assume that this is the bouncy triangles but I couldn't understand how to switch. If the rev-gravity ones are in here, I have yet to see them. Perhaps after 18? Edit: Again, I'm an idiot. Continuing game.
