Thanks for checking it out. I do agree, it's a bit lacking in fun feedback - I really wanted to included quick animations of comets and stuff pummelling the Earth, plus transitions between the areas. But time was lacking, as was my knowledge of LÖVE. Perhaps I'll add to it now and then when I get a chance, after the jam voting has ended... though I am considering make a more in-depth, whizzier new version in Godot.
To be honest, I think the reasoning for downgrading Pluto as a planet was scientifically sound, but I felt the need to include it - mainly because its got a heart and therefore needs love :)
