Thanks. I did alright in the jam (though to be fair, just about every entry in that jam deserved 1st place; there was some amazing stuff that was submitted).
I did get around to (finally) updating the game to include a built-in minimap that shows where you have explored. Unfortunately, the game never tried to track map progress beforehand, so loading a game will still leave you with a blank map slate (everything else in the game save is fine).
I wonder if this would be a decent indy for speed running...?
