Thank you for your feedback! I'll let my colleague speak to your controls feedback (I think I'd like the schema you suggested, actually), but I wanted to give credit for the platypus idea to my spouse (not in the jam technically, but helping from the sidelines). I was trying to think of a protagonist for a bioluminescent cave environment, and he happened to know platypuses can actually glow under UV light. Also, I personally like to think (though this is not canon) that his fast fall is due to his juicy platypus booty. But I digress.
Thanks for playing, glad you enjoyed! <3
