This looks AMAZING. Gives me very strong shadowgate plus roguelike vibes. The aestheitcs slap. That said I....kind of hate the keyboard control scheme. It took me several minutes of alternating between trying to move my guy and looking at your instructions to realize that this is the only game I've ever played where X is not down. I'd also consider adding keypad movement for those who prefer that for each access to orthoganl and diagonal movement. Out of curiosity, if it's left click to interact anyway, why not left click to move to a tile? ('I didn't want to do pathfinding in a one week jam game' is an incredibly valid answer). Another comment coming (I'll put that one on the jam page) once I've spent some time playing the game, these are just first impressions.
e: holy heck, I just noticed by accident there's no limit to the number of consecutive tiles of water you can leap over. That's awesome. I had assumed you could only hop over one or two tiles. You may be naked, amnesiac, and unarmed, but at least you're an olympic long jumper!
