^Fair enough. Still doubt there's any kind of deeper secret regarding the eggplant though.
How is it a reference to Kid Icarus? What? Just because of those eggplant wizards? Ice climbers has eggplants too...
Anyway, I kinda doubt it does much else, but go nuts looking, it would be nice if there is something else.
I guess my logic is that being an unforgiving platformer with projectiles and an upgrade system, Kid Icarus is a closer relative than Ice Climbers is to Spelunky. But you're right, could be that too.
