The character artwork featured on the thumbnail looks great, but the tiles in the game don't visually match - although, looking at your other comments, I see now that you did draw some tilemaps for the background, and just had technical issues getting them into the game. (Sad, but understandable, since this is a game jam with a deadline!)
If you ever update the game more with those tilemaps that you couldn't get in, I'd love to check it out again!
