Incredibly cool. You weren't lying about difficulty, some areas are borderline precision-platformer hard. That one level with lots of bounce pads and spikes was especially devious.
I got to the wizard, but unfortunately the game bugged out for me: I jumped above the map, my frog disappeared (turned invisible? Hands reacted as if I was running underneath when I pressed around directional buttons).
I think it would be easier to beat it for the second time, so I would replay it a bit later.
Amazingly sweet puzzle platformer, good stuff!
