I feel like an option to throw would be nice. I understand that that is essentially what 'launch' is, but I mean that I would like for thrown items to have some of their own physics, be it rotation, or drop, or both.
Additionally, space bar eats the butterflies, but it also catapult the page downwards. And expecting someone to be able to do the red thing on the very first floor when the frog doesn't stay still (constantly moves to the right), its very hard to do.
