Just four levels (+ Olmec) of random ideas that came to my head. They are pretty difficult, but doable. I have tested (almost) every little thing in each level to make sure it works and is passable.
1-3 is pretty much entirely luck-based, just a heads up.
I have thought about adding more levels, but I might be running out of ideas... :/
Some you may enjoy, some may make you rage,
but all I hope for is you have fun!
